I wonder if those making furniture are just doing it to stave off boredom after cashing in millions of tech stock profits. I've already seen exactly this sort of pattern in a few people I know.
There's definitely some truth to that. I've grown to hate technology over the past decade or so, largely because I'm a technologist who believes that technology should exist to make our lives better and the entire modern industry seems hell bent on doing the opposite. Consequently, I'm considering radical lifestyle changes that I am forced to admit would probably not be possible if I had not saved a good amount of money that I earned working in technology. And I don't even make that much because money was never a big motivator for me.
When I was a manager for a few years I started wood working as a hobby. If you have the builder/creator itch then when you stop building software then you will need an outlet for your itch. When I went back into software development, I have not touched the wood working.
Wood working, classic automotive restoration and several other hobbies tend to scratch a similar creative itch that software does. They each have a element of perfection above perfection, unlike software success in a project is easy, but similar to software mastery is difficult.
I'm neither rich, nor do I work as a programmer or software engineer, but I have found woodworking to be extremely rewarding. Wood is an amazing material, and there's thousands of years of woodworking experience available in books, online instruction videos and DYI guides so it's relatively easy to get into. It's nice to use one's hands for other things than a mouse/keyboard.
