I vote for 3. I've been thinking about doing something similar because it has become obvious to me that most software these days is a net negative and actively hinders progress (both personal and societal).
I know there are great projects out there, but they're few and far between, and regardless of how I feel about my own work and abilities, I seem to struggle to impress the right hirers (where I have an easier time getting in at companies I dislike :/).
Thanks for reading my longggg post, and thanks for the vote!
