In the real world there aren't any true exponentials, everything eventually saturates as ultimately physics related constraints hit. You can only compress information so much, transfer it so quickly, you can only access resources at a certain speed, only so much energy is available, etc.

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. Recursive self improvement is ultimately limited by everything else that cannot move at the speed of electricity.

Yes and this was very hard and required massive real-world resources. We didn't just get a sudden flash of insight by thinking real hard about how to make ourselves smarter. Yet that's always the story that underlies any claim of RSI. You can always phrase things generally enough to make any kind of AI-led improvement look like "RSI" no matter how short-term and tightly bounded, but that's just not helpful.

Billions of years of evolution hasn't hit on it. Seems pretty unlikely.
