I would agree, but might add that evolution doesn't have 'goals'.
Is that the point you were trying to make?
Convergent evolution exists for at least some adaptations though, like the eye. It’s not unreasonable to think that there may be some sort of equivalent convergence which creates a high general intelligence adaptation given enough time, at least for social creatures.
I think it’s pretty much impossible to know whether intelligence is a convergent adaptation without some kind of perfect simulation of evolution over billions of years. You’d have to tweak starting conditions and see if you kept getting smart creatures.
There are many reasonable assumptions one could draw from the fact.
Says nothing about this:
> biological general intelligence is the end goal of evolution
Intelligence is simply a special side-product of evolution, there is nothing general about general intelligence. Many organisms can thrive without it.
There is also a non-negligible chance that all organisms would die out before reaching intelligence. We are fortunate to live in a world that produced us.
