> Ten years ago, I would have kowtowed to someone elite enough to build something like this.

I'm afraid it's an elite skill in the sense that juggling is also an elite skill. It's impressive for the first few seconds you gaze into it, but once the novelty factor wears off you understand that it's wasted effort that leads to a project that suffers from a massive maintainability problem, is limited in which platforms it can run, and brings no advantage whatsoever. It's an gimmick that has no practice use.

This is the software development equivalent of an amateur guitarist posting shredding videos on YouTube.
