This is making the assumption that AGI is computationally expensive rather than just requiring of a particular algorithmic approach. It may be possible (and in fact I'd expect it to be so) to replicate general human-level intelligence with significantly less raw computational power than that embodied by the human brain.
Evolution does generate highly optimized systems but generally only when those systems have been around for tens of millions of years. Human-level intelligence has only been around for what, 50k - 100k years? We're probably still more in the 'just works' phase rather than the 'streamlined and optimal' phase.
