I think as a dev if you're just gluing API's together or something akin to that, similar to the office jobs that got replaced, you might be in trouble, but tbh we should have automated that stuff before we got AI. It's kind of a shame it may be automated by something not deterministic tho.

But like, if we're talking about all dev jobs being replaced then we're also talking about most if not all knowledge work being automated, which would probably result in a fundamental restructuring of society. I don't see that happening anytime soon, and if it does happen it's probably impossible to predict or prepare for anyways. Besides maybe storing rations and purchasing property in the wilderness just in case.
