A pig's brain has been frozen with its cellular activity locked in place

What percentage of your life being enjoyable vs horrible suffering makes it worth living?

Maybe you're 80 years old at the time of storing your brain.

Suppose after being revived that regime with capitalist incentives holds for another 200 years during which you live as a brain in a jar, but some cultural revolutions later you are liberated and then proceed to live 10'000 years across any number of bodies and circumstances, which means that in your lifespan of ~10'280 years (not accounting for being in storage) you experienced horrible suffering for about 2% of your life.

This is as much of a contrived example as yours, aside from maybe good commentary on your part on human ethics being shit when profit enters the scene.

Or maybe after 200 years you expire, having at least tried your best at a non-zero chance of extending your lifespan, instead leading to your total lifespan of 280 years being about 71% suffering. Is it better to not have tried at all, then? Just forsake ANY chance of being revived and living for as long as you want and conquering biology and seeing so much more than your 80 year lifespan let you? Should absolute oblivion be chosen instead, willingly, a 100% chance of never having a conscious though after your death again (within our current medical understanding)?

What about the people dealing with all sorts of horrible illnesses and knowing that each next year might be spent in a lot of pain and suffering, even things like going through chemo? Should they also not try? Or even something as simple as all of the people who look for love/success in their lives, and never find any of it anyways and possibly die alone and in squalor? They knew the odds weren't good and tried anyways. A more grounded take would be that those preserved brains are just left to thaw and you probably die anyways without being turned into some human captcha machine, at least having tried. Is it also not worth it in that case, knowing those both potential alternatives?

In this case, the damage is total. The degrees end here, it reaches a binary state: from alive to dead. And then something else entirely says they are the dead person and they are alive.

The question is, does society accept a complete switcheroo? The individual died in the process, they cannot give an opinion on this. The copy is another entity. There are no degrees, it's all absolutes with this process.

Nematode worms have an oxytocin analogue called nematocin that is known to influence learning and social behaviors like mating. As far as I can find, the project doesn't account for this, or only minimally, but aims to in the future.

It's not surprising that immediate short-term behaviors like movement depend mostly on the faster signaling of the connectome. But since we know of other mechanisms that most definitely influence the connectome's behavior, and we know we don't account for those at the moment, it is not accurate to say that the connectome is "all the information you need".

I agree that mapping the connectome of the human brain is impractical to the point of impossibility. But even if we could, the resulting "circuit diagram" would not capture all the details needed to fully replicate human cognition. Aspects of it, sure. Maybe even enough to make it do useful tasks for EvilCorp LLC while being prodded with virtual sticks and carrots. But it would be incomplete.

Most likely they're just preserving the tissue, but not the consciousness

It could be better, it could be flawed in the same ways, it could be flawed but in different ways, or it could be worse altogether. Compare our current lives with someone a century ago. Two centuries. A millenia. Plus hey if you wake up and the oceans have boiled off, there's solutions to your continued existence then.

> I know for a fact that I will grow tired of existence.

I think that's the main part - ceasing to exist should be a choice. It wasn't one to be brought into this world, but inhabiting it and going out of it should be done on one's own terms and when having lived as good of a long life as one might want to. For some people that will be close to a century. For others that might be a thousand years. Who knows, for some it might be a million years.

If this is all thought experiments, why not? At that point, why even care about waking up in a capitalist dystopian hellhole? Might take a few centuries to overthrow them but it's not like that sort of life is the end point of humanity. And if it is, at least you'd know that for sure. Or maybe it's nuclear winter. Or something closer to a utopia, or at least something where everyone's basic needs are more or less met. Asking for guarantees doesn't work either way.
