If your guys do not clean, carve out, flush out, whatever the ai from the system it does not matter which means they use to control parts of previous system - they may use typewriterz, ride aroud on stone bikes, whatever, all that does not matter as long as they do not understand the system and clean parts where ai may be.

Okay, they use perforated paper to program sequence on a steam pressure cooker - what has it to do with the ai inside of it and wifi as integrated part of ai version IOT, where he stores its hidden backup - nothjng, it has nothing. Yeah it may be sloooow there(or may be not), but it does not mean it can't strike.

Okay, pressure cooker maybe a far stretched - universal matter synthesiser, how much brain it can have - it probably a complex machine, and what if it the only source of food here. Navigation, engines, reactor, electricity smart routing boxes, load distribution system, life support, etc. Maybe the ai is distributed system on its own, in every preeure cooker there is a little bit of it - no information about that in the q.

A space ship it is a system of connected complex machines and it has to work in particular way, coherent, at proper speeds and feeds, you just can't shove random equipment with different specs and expect for eveything work fine in cases if it makes some real work and not just an interface.

Replacing peripheral interface does nothing, replacing core equipment breaks coherence of the system, making a big question - can it still work or not, and most likely not, how fast it breaks, will it blow up(not a trivial question, very important for a rocket, I guess for a space ship also a legit concern).

• there is a similar/different less significant compatibility problem - its name is "porting software between windows linux macos" - you guessed it, it is pain in the rear for anything more complex than some applet, with all the expirience and libraries for cross compiling - it still does not work the same.

And here u throw guys into a system they do not know and wish to replace stuff randomly and rewrite stuff from scratch - it requires a lot of time and a lot of human resources and not necessarly possible, and you will need to make equipment/hardware from scratch as well, at least interfaces(which not necesarly helpful, as I said earlier) and not always possible - why is way beyond the scope of the q.

What they have to do is to understand the system, classify identify components, especially ai related. If ai is in every poressure cooker and they can't erase reset rebuild components - then not much luck for them.

If ai is in some datacore, data center, on neural chips - reset it, place it in chroot virtual environment, make safequard ai, different monitors etc - harden your security, harden you against rebellion.

It not necessarly a 100% success, as you really need to go trough all leacks of intel(if you can't......

And there are options after options, scenarios after scenarios, variations after variations how situation can develop - question does not provide enough information about situation and system and all that.

Maybe, they chip out ai datacore and most of other devices are operated by text commands idk some JSON bus, because founding fathers did forsee the necessity of monitoring and be able read stuff there(real situation), be able to overwrite stuff from a calculator. Etc etc. And ai even being evil, keept it that way to remove suspicion and whatever other reason(there can be a list of those, valid ones)

main points

• Guys have to understand what they do - and use proper solution

• young people may not know, but old - already do backups

• factory reset is a thing even today, bring trash you can factoty reset, for ai you can control (there are ways to do it rigth, just use dumber ais, more of them)

• it is possible to clean ai if you understand system used, at least principles. AI can't emerge sporadically, we see that in efforts of todays to make an ai work. So treshold for super evil super smart ai is way higher than tech level you propose, and exceeds our current level. There are limits, there are conditions - it is not magic.

• absence of ai does not mean everything is good - viruses of today show that, so whatever hardware left can be problematic. Some desync of actions may lead to problems naturally. Best one can do is to monitor for everything you can to detect abnormalities and be prepared to deal with the problems, fix them etc - detecting and understanding and cleaning system bit by bit.

• in your question there is not enough information - it is possible to create situation and set resources available when your solution may be the only one, but it requires a lot more work on your side.

• most likely tech is tech of previous generation, or if most of it lost then highest one they can get, chips from 80's-90-00-10-20-30(?) - because more you leave to be handled with already present components, which you didn't made, more there is places for potencial problem, for the ai black box situation as it is present in the q. By lowering your tech for tapes (and really it not necessarly easier than other solutions, satrun rocket engines are example - we can't make them today, but things are more interesting) more you leave to be processed elswhere, more things are out of your control.

Perfect situation is the same tech level, with factory reset equipment, or any hacked T100 options - make your own evil ai, which evil against that evil ai - if it can go wrong, make it go wrong in a rigth way.(but learn your lessons really, there are safe ways)

• it not possible to ommit alternative solutions, because how superficial the q is, it brings irresitable urge to bring some improvements for situation, everyone tries in a way they can.

• if you like that steampunk stuff(how it is called whatever) just do it, there is no reason for it, but just do. (Do not expect me to read/wahtever however, even if you pay, but it does not mean there aren't people with the same vibe) AI's and movies most books they soo lost, even if there are good approaches, nobody uses them, lol. Evil ai trope is beyond repair.

Okay, pressure cooker maybe a far stretched - universal matter synthesiser, how much brain it can have - it's probably a complex machine, and what if it controls the only source of food onboard.

A space ship it is a system of connected complex machines and it has to work in particular way, coherent, at proper speeds and feeds, you just can't shove random equipment with different specs and expect for everything work fine. In cases of it making some real work and not just acting as an interface.

Replacing peripheral interface does nothing, replacing core equipment breaks coherence of the system, making a big question - can it still work or not, and most likely not, how fast it breaks, will it blow up  (not a trivial question, very important for a rocket, I guess for a space ship also a legitimate concern).

There is a similar/different/less significant compatibility problem - its name is "porting software between Windows Linux MacOS" - you guessed it, it is pain in the rear for anything more complex than some applet, with all the experience and libraries for cross compiling - it still does not always work the same.

And here you throw guys into a system they do not know and wish to replace stuff randomly and rewrite stuff from scratch - it requires a lot of time and a lot of human resources and is not necessarily possible, and you will need to make equipment/hardware from scratch as well, at least interfaces  (which are not necessarily helpful, as I said earlier) and not always possible - why is way beyond the scope of the question.

What they have to do is to understand the system, classify, identify components, especially AI related ones. If the AI is in every pressure cooker and they can't erase, reset or rebuild components - then they're out of luck.
