Ask HN: Transition away from CS job as main source of income

I am a dev with 10 years of experience. I don't have much savings because I lived in a country with low wages up until 2020.

With the AI apocalypse staring at horizon, I am wondering if it's possible to transition to some other income source. My plan is to develop a secondary set of skills to which I should be able to fall on when I lose my job in next 3-5 years.

Anybody tried something like that?

I tried getting weekend only job at local Caravan body shop company but they didn't give me chance because I did not have any experience with the mechanical tools and stuff, I offered to take no pay and learn with them but they felt that I will slow them down. What else HN think I should try? In which skill building should I invest my time and money?
