Pretty good Solarpunk prompt with some medium-hard sci-fi thrown in.

I can't imagine hobbyist forgetting how to do lithography. But it's a lovely video. the electro migration stuff scares me

The "forgetting" isn't individuals forgetting, it's about institutional memory. Individually, there might be plenty of folks who can build chips, but they might live too far apart, or there's no money in it, or whatever other mechanism which causes things to be built and the technology to continue. There's a massive bootstrapping issue.
