It's lacking the biology part and physics part, and chemistry, and ....
Some of the sections are just out of context and become showing offs(like the keyboard part. For a hardware position that is not enough, for a software position that's non-relevant), which doesn't mean more sophisticated, just different interest domains.
Your comment sums it up well but I don't see what the problem with that is. Expanding arbitrarily into different interest domains without any limits (upper or lower) to detail seems exactly the point of this repo. Which seems great.
