Oh, but..
Using evolutionary algorithms to create an AI is certainly possible. It worked once, after all.
That assumes that intelligence (and then extelligence) is an inevitable result (or at least a "step upon the way") in the evolutionary chain. Another 'solution' might exist to the 'question' of "how does something
outcompete everything else survive" that isn't intelligence. Although being inteligocentric homonids we are as biased towards intelligence as we are towards the humoid bodyshape, when envisaging the so-called 'end result' of an evolutionary chain.
Possibly more so, as we can see a lot of other body plans out there, but apart from possibly the 'hive mind' concept (emergent so-called intelligence from the interaction of separate yet related entities of very little 'mind' in and of themselves) we really haven't seen (or at least recognised) any other answers, or can fully comprehend the likliehood.
Also, just as we're also on a world dominated by carbon-carbon organic chemistry, and thus <random-other-life-system> that might have arisen has been swamped out (at least within our currently recognised biosphere, who knows about what lies in the mantle!) our form of intelligence, and the rudimentary progressions of intelligencia within the rest of the biota of the planet (response to stimuli) might have precluded (or be hiding) something as seemingly perverse as a non-inteligent crystaline solution[1] towards universal dominance that might otherwise have arisen. Noting that I am far from able to justify
that as a viable 'solution' (it's difficult enough to succinctly explain the intermediary stages).
[1] That is "solution [to the answer] that can be defined as 'crystaline'". Not a solute within whose molecular mass is a dissolved crystal-forming substance. Although the latter would at least be a precursor to the former, IYSWIM.
