It's not hard to learn just takes time. Easiest route is to find a job that wants experienced programmers but doesn't care if you have rails experience, there's plenty. Second best route is to just build something with it. For context, personally I hate it 3.5 years in, but I can see why people like it. I would learn it because you have colleagues that use it, or there's companies you like that require it. Most people that think it's a silver bullet are just hopping from something they don't like; you'll find just as many people doing the opposite if you ask around.

On point 4 it does make you more productive for run of the mill CRUD work, but now that AI has gotten so good, I'm not actually sure that's a major benefit. I.e. it replaces configuration / boilerplate with magic, but AI can write boilerplate / pattern match really really well. I bet writing in Go saw a huge boost from AI.

Food for thought, thanks!
