I don't think you are estimating correctly the amount of energy spent by "evolution" to reach this.
There are plenty of bodies in the universe with nothing like human brain.
You should count the energy not of just Earth's existence, formation, Solar system's formation and so on, but much of the visible space around. "Much" is kinda unclear, but converting that to energy so big, so we shouldn't even bother.
It's best to assume we'll never have anything even resembling wetware in efficiency. One can say that genomes of life existing on Earth are similar to fossil fuels, only for highly optimized designs we won't like ever reach by ourselves. Except "design" might be a wrong word.
Honestly I think at some point we are going to have biocomputers. I mean, we already do, just the way evolution optimized that (giving everyone more or less equal share of computing power) isn't pleasant for some.
Same logic would suggest we’d never compete with an eyeball, but we went from 10 minute photos to outperforming most of the eyes abilities in cheap consumer hardware in little more than a century.
And the eye is almost as crucial to survival as the brain.
That said, I do agree it seems likely we’ll borrow from biology on the computer problem. Brains have very impressive parallelism despite how terrible the design of neurons is. If we can grow a brain in the lab that would be very useful indeed. More useful if we could skip the chemical messaging somehow and get signals around at a speed that wasn’t embarrassingly slow, then we’d be way ahead of biology in the hardware performance game and would have a real chance of coming up with something like agi, even without the level of problem solving that billions of years of evolution can provide.
