I like the idea of the lowest technology hurdle required to build one such device. Any ideas? Seems like we must be there in terms of inventability now. A good project to work on!

Yeah, I do have some ideas: https://dernocua.github.io/topics/digital-fabrication.html https://dernocua.github.io/topics/self-replication.html https://dercuano.github.io/topics/self-replication.html https://derctuo.github.io/topics/self-replication.html https://dercuano.github.io/topics/digital-fabrication.html etc.

Thanks. I have now read all of that, and think I have a rough idea of what’s interesting you. What are you working on right now?

Your response comment saying "I have now read all of that" was posted 11 hours after I linked you to a bit over 120,000 words of notes on the topic you were asking about (according to 150 * [...document.body.innerText.matchAll(/(\d+)\s+minutes/g)].map(m => Number(m[1])).reduce((a, b) => a + b, 0) on a non-overlapping subset of the topic pages).

Some of that material is a little difficult. How did you manage to read it all so fast? I'd like to hear what you found most interesting.

As for what I'm working on right now, probably seeing the sunrise tomorrow, but see also https://news.ycombinator.com/item?id=48807996
