>Biology is non-toxic. Biology is efficient. Biology is beautiful. Biology is technology. I have a huge problem, with especially the first two. Biology can be very toxic. Cobra snake venom is a product of biology. Cancer is a product of biology. Both can have horrific consequences for humans. Biology is not necessarily efficient. Take a look at pregnancy and birth and infancy. Before modern medicine and birth control…
Before that it mentioned "Human DNA is 6 GB", but a lot of that is junk and meaningless. "Dead code", so to speak. Hardly what I call efficient. There are plenty of weird things as well. Why can't humans synthesise vitamin C? My cat can; in fact, most animals can. But not humans and most other primates: we lost this ability. This is probably because at the time we didn't really need it as we got enough from dietary s…
... so far as we currently know.
DNA is only mostly software; it's also a physical molecule. Many of the columns in a DRAM chip look like a waste of capacitance until you know what alpha particles are and what ECC does.
> the blind spot in our eyes, which is there for no real reason
It's there for a very good reason, the optic nerve connection. Only cephalopods have figured out a better solution, and it's not at all clear that it would work for humans.
Our eyes have to tolerate a lifetime of much-higher UV exposure than sea-creatures, for starters. Cephalopods' optic nerves grow in from the retina toward the brain, and there's a huge bundle of complicated connections to make where they "meet in the middle". Vertebrate optic nerves grow out from the brain and embed themselves in the retina, so there's no wiring problem to solve.
