That's fair. It depends on the goal. I'm not trying to change careers. And I didn't get that sense from original poster. I'm mostly interested in prototyping or addressing niche productivity issues. But I feel I learn quite a bit from seeing what the LLM does and asking follow up questions or looking things up. I've been around software dev a lot so that helps with knowing what to ask sometimes. My main point is if someone is interested in building software, they should start building as soon as possible. Don't feel you have learn everything first.
