Give me one datacenter, I'll keep it under control all by myself.
Now, if some dumbasses start hooking up their data centers to...I don't know, like--robot factories? That sounds like a risk to humankind.
I'm not sure what your point is. No one thought RSI would break the laws of physics.
Specifically: AI ultimately has to live in this reality and face the corresponding limitations. These companies have already consumed much of the world's supply of computing power for the next several years, and they're burning vast sums of money to keep the improvements going. RSI won't learn for free, it won't extract massive cost reductions without up front expense, it can't build factories faster than humans can work out related societal matters, it can't magically pave the deserts with solar panels for power or build and run nuclear power plants and more.
Point is, the cost of progress is already approaching the limits of what even the richest countries are able to bear (without war-like mobilization), and to bypass those constraints would require a supposed ASI to construct its own parallel supplychain from scratch without having much ability to directly interfere with reality.
You are constructing a straw man of your own making.
Plus, "we must pace the frontier" implies that the argument is that the frontier is moving too fast, but if RSI can't move faster than the rest of reality and the models needed for RSI are already nearing the limits of current human reality, RSI can't move much faster than we can improve reality.
