We can surely build more efficient and capable hardware than our current evolved wetware, since all of the details of how to build it are generally externalized. If the chips had to fab themselves, it would be a different story.

The software is a different story. Sure, the brain does all sorts of things that aren't necessary for $TASK, but we aren't necessarily going to be able to correctly identify which are which. Is your inner experience of your arm motion needed to fully parse the meaning in "raise a glass to toast the bride and groom", or respond meaningfully to someone who says that? Or perhaps it doesn't really matter - language is already a decent tool for bridging disjoint creature realities, maybe it'll stretch to synthetic consciousness too.

All of computation is realised by very few arithmetic operations. Then test energy efficiency of wetware and hardware on those operations. Then any difference can be attributed to algorithms.
