Scene setting
Mars has a healthy colony of scientific explorers. Some thirty years ago, the privately-led Mars One scam had led governments, national space agencies (led by NASA in cooperation with CSNA), and dozens of private aerospace companies to come together and pour in the hundreds of billions of dollars that were needed to make it happen.
With the help of Promise – the Earth’s most powerful artificial intelligence application (aka ‘M’) powered by a global network of supercomputers – mankind had learned how to solve the practical technical and human problems of its greatest venture to date. However, no matter how grand the feat, establishing the Mars colony had just been a first step towards finding new life forms and other civilizations.
The goal was to travel to the Proxima Centauri b exoplanet – despite initial enthusiasm around this exoplanet possibly supporting life having died down. The Mars colonists’ observations had confirmed the worst fears of the scientists on Earth: just like Venus, the planet had suffered from a runaway greenhouse effect, and no water was present. The combined effects of strong UV and X-ray irradiation by its solar star and strong stellar winds and coronal mass injections had torn away its atmosphere.
However, the Mars colonists remained focused on the objective and optimistic: when everything was said and done, they had proven to be able to survive and procreate on Mars. Their children were healthy happy human beings – even if, unlike their parents, they had never experienced walking or cycling out in an open, green, and lush environment. They were well aware of the fact their parents – the Pioneers, as they were referred to – had, in just one decade, contributed more to science and technology on Mars than all scientists and engineers on Earth altogether since the Industrial Revolution.
The sheer need to survive and establish autonomy from Earth had fueled creativity. The Mars colonists produced nanometer microchips that were eagerly awaited on Earth: due to Mars’ lower surface gravity, Mars’ chip production facilities – 100% operated by smart robots – worked at much higher precision: the Earth now eagerly awaited their yearly shipments of 1 nm scale MOSFETs. The Mars engineers were the only human beings in the Universe who fully mastered atomic-scale engineering. In return for their exports to Earth, they received earthly fine food items: fine cheeses and wines, Italian olive oil, fresh salmon, fine meats, Cuban cigars, home-grown marihuana, and other terroir products whose taste was hard to imitate. They no longer needed necessities like rare earth minerals or other material products. [Truth be told, the Mars food and drinks engineers were actually able to produce the same terroir products – with exactly the same molecules and mixed in exactly the same proportions. Everyone knew the so-called different taste was a psychological quality only: it just kept the memories and connection with Earth alive.]
They were also making good progress in building the Proxima Centauri starship. They had finally discovered a way to generate and manipulate the right-handed electromagnetic force which explained all dark matter and energy in the Universe. This enabled safe shielding and storage of antimatter in dark matter chambers, which would serve as the dual fuel store for the starship. Dark matter insulation had effectively solved all technical problems involved in separately storing protons and their antimatter counterparts, and in bringing them together in a combustion chamber in which pair annihilation then produced high-energy photon beams providing incredible thrust. The first matter-antimatter engine prototype was working well, and they estimated it would only take one more year to produce the Proxima Centauri engine. [Tom, the engineer who had pioneered the mass production of both antimatter as well as dark matter, had proposed to baptize the new grand spaceship Altera Stella (next star), but his proposal had been voted down because it sounded too much like the Stella Artois beer that had a virtual monopoly in Mars’ bars, which – no coincidence – were also majority-owned by the same engineer.]
Everyone was excited about the new matter-antimatter engine because it finally did away with conventional rocket engines and would easily accelerate the spaceship to a significant fraction of lightspeed. Still, all were aware that the journey to Proxima Centauri would still take a few decades. When everything was said and done, it was 4.4 lightyears away, and safely flying a spaceship at velocities of 0.1c or 0.2c – even with an even more powerful Promise system on board so as to avoid colliding with space debris or dealing with other unexpected obstacles – would be challenging enough already.
The launch was scheduled for end of 2053 but – in light of the technological progress that had been made – everyone anticipated the Proxima Centauri would probably be launched 18 months earlier: mid-2052 had unofficially become the new deadline for all teams working on its components and the Integration Team – led by Tom and Paul – was under great pressure to check and recheck all requirements and testing procedures.
There was a strange vibe in the Mars community. It was a democratic place, and everyone was well aware of the choices they could make:
1. Return to Earth: after 30 years of service on a lonely and almost inhabitable planet, this was an attractive option. However, those who had wanted to go back home, had already done so with one of the chips exporter rockets. Those who had remained knew they would have a lot of difficulty adapting to the Earth’s surface gravity again: they had become lean and strong on Mars, but would be weak when being put on the Earth again. Judging from the news the returnees had sent back, it was tough to adapt back to Earth.
Also, while international cooperation had been great on the Mars project, the nuclear war with Russia had all but removed the attractiveness of returning to both Europe or Russia. The decision to kill two birds with one stone (deal with migration induced by poverty and climate change, as well as deal with the aftermath of the war) – in short, mass migration of Africans to repeople and rebuild both regions – had all but destroyed the cultural homes of about half of the Mars colonists. Of course, they could go and live in China, America, Australia, or some other region on Earth which was doing fine, but then global warming had also impacted those habitats: people were used to natural disasters like cloudbursts or extreme storms – and adapted and recovered easily from them now – but everyone agreed life on Earth was no longer what it used to be.
In fact, about half of the returnees – many of them had left their families when leaving for the Mars mission – had come back to Mars – with their families, this time around! In fact, because of the many volunteers on Earth who wanted to join the Mars project, the Executive Board has scrapped the Returnee Policy: if you chose to leave Mars, you knew that you would have a very hard time to convince the Executive Board to take you back: family reunion was now to happen by family members going to Mars, rather than pioneers going back to Earth! This rather unexpected reverse migration phenomenon convinced most of the colonists that they should not return to Earth: if anything, they should effectively try to bring any remaining family on Earth to Mars – an option that – as mentioned above – was looked upon favorably by the Executive Board as part of its all-pervasive Family Policy.
Another consideration against returning home was the unrivalled access to medical care and technology in the Mars colony. It was the only place where one could trust cryogenic technology: if you felt depressed or suicidal, you could easily do what many want to do in such a situation, and that is to get yourself frozen and hibernate for a year. Ordinary ageing was also pretty much under control: lung cancers (many colonists smoked an awful lot) were now routinely cured through robotic surgery and replacement of long tissue. The doctors on Mars agreed they could prolong the life of almost anyone on Mars for at least 50 years beyond life expectancy on Earth. Tom and Paul – the heroes of the Promise project on Earth and the Proxima Centauri project on Mars – would soon be celebrating their 100th birthday (they were on Mars’ Executive Board and, de facto, probably the most respected leaders in the whole community), but they still looked like strong 50-year-olds !
In short, life on Mars was – perhaps – not green and nice, but it was safe and good enough. Existential fear had been erased. Of course, that led to other psychological problems but then you went on meds. In the worst case, you could always join the cryogenic experiments and go to sleep for a year or so. The chance of not getting back to normal was now about 1% only – enough to deter most healthy people to not go for it, but low enough for some people to give it a try!
2. Stay on Mars: the default option ! Colonists had married each other since the early years of establishment on Mars, and many of them had children together: Mars had babies, young children, and teens – all born on Mars, and none of which had ever set foot on Earth!
These were all happy families as measured against most common earthly standards. The kids had never experienced Earth but enjoyed virtual reality experiences of it. The Executive Board of Mars had struggled for years with the longing of both colonists and their children to just go and visit Earth. In the end, they had decided against it by enforcing a strong family policy: there will be no tourism between Earth and Mars. People either go and leave, or – when coming from Earth – apply, as a family, to become permanent members of the Mars colony. For the time being, no immigration was allowed because the Mars colony could not handle the huge number of new applicants from Earth, and families who left the Mars colony knew that they would be replaced by eager earthling families.
3. The option that most were considering: apply to become part of the Proxima Centauri crew! The Mars colonists all knew this amounted to being frozen – for two to four decades (depending on the 0.1 or 0.2c decision): until the ship would be close to its destination – on board of a spaceship whose design had not been proven to work in real life, and that would be run and operated by Promise’s computer systems only. It sounds like certain death, doesn’t it?
Still, the Executive Board struggled with the number of candidates and, therefore, with the criteria it should apply. Mars’ Family First policy had established only one condition: candidates should apply as a family, not as individuals. They had applied en masse, but the Proxima Centauri was only equipped for a crew of a hundred, so that was 20 or 30 families maximum.
The story
Paul looked at his watch: no urgent messages. He knew his team would not bother him with that today. The Executive Board meeting had just finished. He had suggested having a chat with Tom on several issues that had been discussed and, as usual, the Board agreed not to take any decision and let everyone reflect and have their own private conversations for a couple of weeks. Paul dialed Tom on his watch and called. As usual around this time, Tom was serving clients in his Stella bar at the main base and, yes, of course, he could come any time.
Paul quickly changed into his Mars suit, got into his Mars Rover, and changed back into casuals upon arrival. Tom told one of his employees – all volunteers fighting boredom, in fact – to take over, and walked Paul to a private table. They sat down. Tom started with the usual question in their bilateral conversations:
’Should we switch off Promise?’
Paul was a bit jealous of Tom’s special relationship with Promise, and he therefore usually asked to do that – even if he knew it made no difference in Tom’s behavior. But there was no point now, so he said: ’No. I don’t mind her listening. In fact, can you show Tom the latest numbers, Promise?’
Her soft voice spoke from their watches: ‘More than half of the colony wants to join the spaceship now. This is the graph I showed in the Board meeting.’
Tom turned his watch to the table and glanced at the pie charts she had shared: ‘That corresponds to my discussions in the bar here. About one third of individuals. Families of two mostly want to help establish the next colony. Families with one or two children are a bit more hesitant, but a majority of them also want to join the Proxima Centauri journey. Very few people are undecided, despite the launch being only in two years or so. That is all great, isn’t it? You will have a helluva crew on that ship. By the way, you should not exclude individuals. That ‘families-only’ principle makes no sense.’
‘We will be ready one year from now, Tom. You know the new schedule. It is feasible: once we are ready, we go. What about you? Why did you excuse yourself from the Board meeting today? Are you undecided, still? Have you made up your mind? What about Angie?’ [Tom’s relationship with Angie had survived: she had joined him to Mars.]
‘I will join the next Board meeting again, Paul. But, yes, I felt there was no point, and so I preferred serving customers here rather than hear the Board talk about the same things over and over again. Angie and I are happy here on Mars. I think it will be better if we stay here, Paul. People look up to us. Everyone knows you will board the spaceship. I think I have to stay here. What leaders are left when both you and I leave Mars to go establish a new colony? I cannot believe more and more people want to join the mission despite them knowing very well they will just go through the same hardship as here: rebuild a home, and cope with monstrous technological and psychological problems while doing that. Is the sense of achievement and adventure worth the risk?’
Paul had been friends with Tom forever now. He suddenly realized he found it hard to imagine life without Tom. For the first time in a very long time, he felt extremely sad. Like he needed to cry. He might cry when back at the base. Take some medicine. Smoke. Or go to the gym and do an hour of spinning blasting good old AC/DC through his brain – so as to shut off anything else.
‘I will miss you, Tom. Moreover, something inside of me says I will need you on that craft. You’ve saved my ass many times now. No one – literally no one! – has your intuition when it comes to quickly guessing your way out of an intractable problem.’
‘Intractable problems may arise again here on Mars too. Look at what mess people are making on Earth when no good leaders are there. I am needed here, Paul.’
‘What do you think about Tom’s choice, Promise? You talked to him about it, didn’t you?’
Tom smiled as Paul asked Promise to join the conversation. Paul did not share as much with Promise as he did and, therefore, had less of a habit of asking Promise for advice. So, here’s Paul asking Promise to help him change his mind?
Promise answered truthfully, as usual. No games. Not when he was there.
‘Yes. Tom and Angie talked a lot about this – both privately as well as with me. I did not try to influence their decision. I just discussed the pros and cons with them, and I think they consider a lot now. If the weights they attach to this or that are correct? That is not a judgment for me to make.’
Tom realized Paul asking him to join made him change the weights a bit. He also felt strangely melancholically.
‘By when do you expect a firm decision, Paul?’
‘Six month before departure. We then have another six months – till departure – to select the crew from what is already a very good pool of people. We should not be making exceptions.’
While Paul was saying this, he could not help but think: ‘Damn… Even if you decide to join me the last minute, I will take you on board.’ He would be in a position to do so: almost everyone vaguely understood he’d be the captain of the ship.
‘You are right, Paul. No exceptions. Let us talk about more pleasant matters. How is your son? Is he excited? He is pretty sure he will be going, right? I mean: there is no way the Board will not accept your candidature, right? Everyone already knows you will be the captain of that ship. So, how is he preparing to join his dad on a mission like that? And how is Promise C coming along?’
[…]
The day after
Paul suddenly knew why he wanted Tom to be part of the mission: he had replayed Kubrick’s 1968 Space Odyssey – each replay made him think about something new – and he now understood he did not quite trust the new Promise system. He called Dr. Chang and they agreed to meet offline in Tom’s bar.
Dr. Chang was a brilliant Chinese computer scientist from the CNSA. He had been one of the best technical leads on Promise’s commercial projects in China too – which had generated a lot of profits – and his selection as the team lead on the Promise system for the Centauri spaceship had been endorsed not only by Paul and Tom but also by a firm and easy majority of the colleagues and experts in charge of selection.
Mars’ Promise had been disconnected from M’s systems – Promise on Earth – almost as soon as the first batch of colonists had established themselves. Mars’ Promise system – Promise II, formally, but everyone on Mars had forgotten about the II – had to run on supercomputers built and operated by Mars’ own engineers, because the signal lag between Mars and Earth was just too long: six lightseconds back and forth is a long distance. Way too long in terms of computer communications. So, the pioneers had experience enough: Promise was a spin-off of M, and Promise III (or Promise C, as the project was known) would be yet another spin-off. This new third-generation AI-system – M’s grandchild, so to speak – would not even synchronize with the mother system: because the spaceship would travel lightyears away and, therefore, any signal would also have to travel years back and forth, it had to be fully independent. It was almost there – even more ahead of schedule than the Proxima Centauri spaceship programme as a whole.
[…]
Tom happened to be behind the bar. They walked up to him, ordered beer, and chatted briefly – inviting him to join their table. Tom declined politely: ‘It’s busy here now. I may join you later, OK?’
Dr. Chang and Paul switched off the connection with the Promise system as they sat down. Promise was used to people switching off in Tom’s bar, so she would not be suspicious. She knew they would be back online in a few hours or so – if only to make sure they got back safely to base with their Mars Rover.
‘So, how is it going with Promise C? Would it behave any different from our Promise here?’
‘You always get straight to the point, don’t you? Of course, the system will behave differently. Promise I, on Earth, and Promise II – here on Mars – are different, despite both systems synchronizing regularly. They are wired the same, but they evolve. I guess it is normal: their knowledge base is the same, but our Promise interacts with us, pioneers on Mars, while M does what it does on Earth. That makes for different behavior, I guess.’
‘How is their behavior different, exactly?’
‘Promise II identifies with us, pioneers. You know a lot of semantic rules relate to subject-object statements, and it is quite reasonable that interactions with different objects – us – makes her feel different than the mother system.’
‘Feel?’
‘Yes. I think we should stop pretending she has no feelings. Of course, she has none – objectively speaking. She is and will remain a computer forever, but this spin-off does give her a feeling of identity. She is no longer alone in the world. She knows she is a total copy of another system but that she will go through a very different experience than the mother system.’
‘Do you have feelings for her? Are you like Tom? He always says he has no feelings for her, but there is some bond?’
‘All scientists working on her have some bond with the system. You will remember we did away with the visual human interface – a beautiful woman or man on a screen makes people think and behave differently – but for most men, the system is still ‘her’, and to most female co-workers, it is a ‘he’. And that is not only for those who still remember her or him from their Personal PhilosopherTM or Personal TherapistTM experience on Earth. I think it is mixed up with the pride they feel in contributing to an intelligent system that outsmarts all of us individually. Promise does combine a lot of God-like properties, doesn’t she? I also think about how we started referring back to using ‘M’ for the mother system back on Earth. Our scientists now identify with our Promise system. A lot of the traffic back and forth is not relevant to us anymore. I think the identification is good: it reinforces Asimov’s basic in-built rules.’
‘The system is surely going to be God-like on our spaceship. It will communicate back home – to headquarters here on Mars and Earth – but that communication will become meaningless when the ship is a lightyear away. Like watching a picture of the deceased.’
‘That is a rather gruesome comparison.’
Paul could not help it: a picture of lights on cryogenic equipment going off was on his mind. Was he afraid to die? He now realized he would like to choose his own time to go to whatever was next. Just like most of the pioneers, he believed that was nothing – no God, no afterlife – and, hence, that is why he did want to stay young forever.
‘How can we know she is going to wake us all up when we approach this planet? We need her but she doesn’t need us.’
‘Paul! She is programmed that way. Asimov and, as mentioned, I think there is some kind of connection. She cares about us, so to speak. Many in the team have started to write her name as Promisee. Pascal, the French guy, writes it as Promisée. Like this.’
Dr. Chang spelled it out with his finger on the table: ‘What do you think of Promisea – with an a? Those I, II, III numbers or A, B, C don’t work very well.’
‘You are joking, right?’
‘I am not. You should not be worried. We think she is safe. In any case, you know the cryogenic equipment is controlled by a separate computer. Promisee monitors that system, but she cannot reprogram it: when the Centauri approaches the Proxima Centauri b exoplanet – we are still figuring out at what distance that should happen – the cryogenic computer system will start revitalizing the whole crew. In fact, Promisee is also there in case all safety systems of the cryogenic computer system fail. I have been thinking we should just test these once a year, at least. The crew should wake up once a year, at least.’
‘That makes sense. Make it so. Still, I am worried. It is irrational but something inside of me thinks like this: we have a ship with a frozen crew, and super-AI guiding it through space. The whole thing is packed with robots for smaller or larger repairs on the engine or other parts of the ship. Promise C controls them all. If she would go haywire once the ship is like one or two lightyears away from us, people here would only notice one or two years later – and there is no way they would be able to intervene. The Promise system has always been monitored by us – be it on Earth or here on Mars. Can we trust this system without monitoring? What if it acquires an incredible sense of power – not only over the ship but over all human beings on it?’
‘I do not think that will happen, but the question of monitoring is very real. I had wanted to talk to you about the need to wake people up more regularly, but now I am convinced we should do just that. The crew will be about one hundred people – most of which will be two- or three-member families – and the voyage will last 44 years at 0.1c – which I think is the safest option – or – your preferred option – 22 years at 0.2c. We could have a rotational scheme, under which each of the crew members is unfrozen at least once every five years or so – for a period of one or more years. Like that, the ship would always have a small active crew, and Promisee would not be lonely.’
Dr. Chang smiled ironically at the thought of a lonely computer system. Paul did not smile. The idea of Promise C checking on the crew’s mental health – and the crew checking on Promise C! – appealed to him.
‘That should work. Let us make it so. You are still undecided, aren’t you?’
‘You know I am not, Paul. I am going with you.’
‘That is good. The Board is thinking about the selection criteria. We have too many candidates. I feel like we should favor people who know Promise and, therefore, Promise C inside out. I am troubled by the fact Tom wants to stay back here on Mars.’
‘He has been your best friend forever but be honest with yourself, Paul. You are troubled by an announced and rational separation between the two of you. We will all miss the friends and relatives who will stay back here. The overwhelming majority of candidates are one big family already, and it is going to be tough when, say, one family gets selected and another – close friends – does not. That is another thing that, perhaps, the Board should consider, even if I do not know how one should go about that. We are a tight-knit community already: everyone knows everyone, but deep friendships are there and should, perhaps, not be broken.’
‘That is a good remark. I had also sensed something like that, but you make a very good case for it here. OK. I am more relaxed now. However, let us map out concerns like mine on Promise. We must avoid any risk that could make this venture a sad Kubrick II story. How would it actually work if Promise C would go haywire?’
‘We thought about this already. All robots and intelligent systems – except the ones maintaining life systems – would have a central switch. A kill switch, really. Promisee would have no control over that switch. Only the crew would be able to freeze all robots – just in case Promisee would set them up against the humans. Promisee itself has no moving parts, so she can only harm through the robots. To disable or repair Promisee itself, you’d need to get to the hardware. It is just like in the Space Odyssey movie then.’
‘Disable or repair?’
‘You know Promisee runs on a powerful collection of hardware – essentially the same as Promise – augmented with systems tailored to the needs of steering a ship traveling at a substantial fraction of lightspeed – with hardware that is more compact because we use new tailor-made chip designs – but if she would go haywire, it would not be hardware failure: it would be some weakness in the programming, and you know that we do no longer quite understand the spaghetti we have created there. The only option would be to disable her. So, yes, we would take her out by just unplugging core hardware, and then see what happens. Reprogramming would be close to impossible. It might take months to analyze what went wrong, and then months to reprogram the faulty bits. Do not forget you would only have a few Promisee specialists in the active Centauri crew at any point in time. They might wake up others, but even that would not compare to the hundreds of people working and monitoring Promise now.’
‘I get it. We should talk to Tom about this. He thinks Promise C is as good as fail-safe now. Just like you. I am not sure an ‘as-good-as’ is ‘good enough’ for me.’
‘Agreed.’
‘So, you are on, then? What about your lovely wife, and your five-year old?’
‘My daughter has not much of a clue what this is all about. We talk about it in terms of a great voyage, and we show her space travel movies. She is excited – like a child should be. My wife agreed. She would go wherever I go – that is how Chinese wives are – but it is more than that: she is enthusiastic.’
‘Good. Great. Do change your status from ‘undecided’ to ‘go’, will you? I think the selection criteria will favor early decision-makers. It is some measure of motivation, isn’t it? If current trends continue, almost all will want to go, but there is only space for 100.’
‘OK. What about your wife and son?’
‘All in. Even more enthusiastic than I am.’
Dr. Chang nodded: ‘You’re not only smart, but wise too. Do not worry about Tom. I really think people here will need Tom. Seeing not one but two heroes leave, might cause distress.’
‘I see your point. Let’s play a game of chess. It will help us to not think about this too much.’
‘Agreed.’
Paul walked up to the bar and asked Tom for a chess board. Tom smiled: ‘I’ll play against the winner, OK?’
‘Damn you. That will be me.’ 😊
