The most terrifying fact about blockchains is rogue AIs you can't switch off

In general, rogue AIs will not be more capable or powerful than humans. Assuming otherwise is religious FUD, and the burden of proof is on the religious believer to show why their AI god is inevitable.
Nice try but you forgot one thing: we could find Satoshi Nakamoto and calmly ask him to make with Bitcoin an EoL like Adobe has made with Flash :) But could we?
On top of this, a rogue AI is by definition hyperintelligent and therefore unlikely to come within a country mile of cryptocurrency.
This sounds as if malware is somehow writing itself.
Also, I doubt that a rogue strong AI would struggle with opening a regular online bank or brokerage account.
I very much doubt disembodied strong AI is possible in the first place. If nature and physical reality in general is anything to go by, intelligence and agency correlate strongly with physical interaction with the environment (e.g. plants are less "intelligent" than most animals).
Even though there's an argument to be made that such interactions can be simulated, research has shown that optimisation algorithms tend to exploit the imperfections of the simulation instead of developing generalised solutions or just become instances of Clever Hans [1].
I'm puzzled how some ML/AI researchers come to the conclusion that an algorithm without access to external information and with no means of manipulating its environment can do _anything_ harmful at all (aside from wasting processing cycles or bandwidth). Malware has explicitly specified functionality (e.g. delete or encrypt files, etc.) that didn't just "evolve" out of nowhere and requires very specific target environments (OS, APIs, access rights, etc.).

I think deep in the ocean or on antarctica makes more sense.
By the way, "air-cooled" does not mean the air cools the chips. In fact, the problem is that the air near the chips gets warm, because the air absorbs the heat and acts as a blanket. Air-cooled means you are pushing the hot air away from the chip and bringing in cooler air. But the absence of air means the problem (or solution, depending on context) never exists in the first place, it just dissipates.
The thinner the atmosphere, the easier to keep cool anything. You need air to retain heat, not to dissipate it. Right, without the Earth's atmosphere, we'd lose most of our heat at night, nearly all of it, and we'd have deep sub-zero temps every night even in the summer, even though we're closer to sun by a lot than Mars, we're still on the outskirts of the habitable zone for a planet.
And the only thing you can do is move the heat because of conservation of energy. There is no other way to get rid of it.
In a vacuum or near vacuum, that is just not correct.

For one thing, if blockchain-powered-rogue-AIs existed they would be hopelessly underpowered compared to ones running on AWS, because blockchains aren’t just magic fairy dust that make all things possible; they are meant to provide decentralisation at the cost of enormous and verifiably wasted effort. Perhaps the OP was thinking of quantum computing; might be worth adding that in there somewhere.
Actually terrifying things about blockchains: The environmental cost of the proof of work; the sheer quantity of grift and fraud on them; the way that supposedly clever people get swept up in evangelising this useless thing. The oxygen that it's sucking out of the room by people wasting time and effort and publicity on it.
And not "oh no, what if we forget how to turn off computers" plus "what if AI, but not anything like the AI that we have".
Not even wrong. Most people never had interest in it in the first place. And even among those who do, it's of no utility in and of itself, only in what it can or can't enable. They will lose interest when the answer is "nothing".
I mean, you sound like a religious preacher. It's sad.
