Very few people have taken the bait. I think we techies over-estimate the ability and inclination of people to make something. Even most programmers don’t want to solder. They may still be technically inclined, but want to be involved at a higher level: Buying the basic stuff and using it as a basis for even more elaborate things.

If you replace 'we techies' with 'most folks' (and especially with 'folks who didn't do a thing with their hands in thei$ lives') nothing would change.
But that was never the worry. The worry is a competitor undercutting you because they do not have to recoup R&D.
