"AI needs a lot of power" depends on where you draw your lines. I can say a lightbulb needs a lot of power if I include all the power needed to generate all the surrounding infrastructure and make the lightbulb itself. Sincere question: I wonder how much power was consumed in the 88 hours required for the Navier-Stokes problem.
It took 88 hours and who knows how many kwh to solve a problem that no other human has solved, and Humans have already solved breaching and destroying systems that can't be accessed over the internet (see Stuxnet).
It feels like you're suggesting the solution to keeping on top of this thing that can outsmart smart humans is to just keep doing smart human things.
