Did you not notice I said "otherwise"?
Regardless, terrorist is a subjective term, and typically one excludes agencies with jurisdiction or organized militia; so the police, ICE, U.S. military, IDF, etc. don't qualify regardless of your disposition toward them. This is why newspapers are usually quite hesitant to use the word "terrorist." There's a good case for calling the CIA (and other foreign-intelligence TLAs) terrorists though, since they operate outside of places where they have the authority to do so. Obviously, it's semantics at the end of the day.
This is what AI researchers/pundits believed until roughly 2020, when it was discovered you could brute force your way to have more advanced AIs (so-called "scaling laws") just by massively scaling up existing algorithms. That's essentially what tech companies have been doing ever since. Nobody knows what the limit on this is going to be, but as far as I know nobody has any good evidence to suggest that we're near the limit of what's going to be possible with scaling.
Quantum computing is not faster than regular computers. Quantum computing has efficiency advantages for some particular algorithms, such as breaking certain types of encryption. As far as I'm aware, nobody is really looking to replace computers with quantum computers in general. Even if they did, I don't think anyone has thought of a way to accelerate AI using quantum computing. Even if there were a way to, it would presumably require quantum computers like, 15 orders of magnitude more powerful than the ones we have today.
Yeah. I don't think AI is really at the highest level of concern for environmental impact, especially since it is looking plausible it will lead to investing in nuclear power, which would be a net positive IMO. (Coolant could still be an issue though.)
