I'm so curious about this; it is nearly universal that software engineers threaten this. I constantly tell my colleagues that I am quitting to start woodworking in a cabin in British Columbia.
My theory is that we are comprised of people who love building and making things, yet at the end of the day we don't have anything tangible to show. Like, my parents (nearing 80 years old) barely understand what I do or how software engineering works, though they are computer-literate. Going back 2 generations and it is incomprehensible magic. But, if I built a cabin or a cabinet or a wooden spoon, I could have a meaningful conversation about it with someone from the last Ice Age (language barriers aside). Maybe it is just staring at a screen 8 hours+ per day leaves the ancient part of the brain wanting.
