You can carve a block of wood into something that looks like a computer. That should be a good start on building a device that can run Linux, right?

Yes. Then you just cast a spell to summon a computer spirit and let it manifest into the wooden block.

Bad analogy, it's other way around for Linux. We are building it to run on wooden blocks that hardware manufacturers are producing.

the first computers were mechanical. Then somebody carved a facsimile with electricity and we got computing. Just because nature founded intelligence in carbon atoms doesn't mean its the only way or indeed the optimal one.

The mimicking is superficial at best. People seem to think that if we just keep marching on the road we're on right now then we'll eventually get there, but I think that's an assumption that is unlikely to be true in the end.
