Build housing/work in the trades (most likely as an electrician/electrical journeyman). Enough work left for someone middle aged for the rest of their working life.
The same thing, tell the computer what to do (I’m a developer, as you may have guessed). If people had zero-cost developers who do what they told, they’d still fail to formulate what to do, how should it work, which tech to use, or to know which tech exists and what it can do. Someone who replaces a developer with AI becomes a developer themselves eventually. The level of AI where anyone can talk to it directly and get what they meant as in DWIMNWIW is a technological singularity, in which all of ours will stop making sense.
