alt Hacker NewsEfficiency by what metrics?
When aircraft can carry onboard oil refineries and drilling rigs you can more reasonably compare them to birds. Without that you need to consider ATP vs jet fuel or crude oil vs a dead fish? Skeletal muscle can be 40+% efficient depending on what exactly you’re measuring.
Going head to head vs evolution in a similar design space with similar tools and goals, arranging neurons for useful thinking, is vary different than increasing top speed while sacrificing just about everything else.

This is a fair point in general, but the whole point in this context is not that human design is more efficient at duplicating an entire organism, but that it can be more efficient at narrowly defined tasks. Evolution has never had the goal 'evolve human consciousness as quickly and efficiently as possible', it just had the goal (and even calling it that is stretching things of course, but let's say an emergent goal) of reproducing organisms.
