That is freaking awesome. The thought that nanobots might be biological never occurred to me. I kinda assumed they would be chemical after seeing a chemist years and years ago being so proud he had made a molecular ring with a ball that tracked around it. He didn’t know what use it was but felt sure it would be a basic part of some nano sized machinery.

I remember that vid of the computer evolution from 30 years ago. It wasn’t in that clip but my favorite one was one that was programmed to go as far as possible in a given time. So one of the things evolved to grow straight up really fast and then fall over so it’s heard was far away from the starting point.
