I've been thinking about this for a full year now, and I'm ready to present my opinion: I think AI assistance makes it easier, not harder to get better at programming.
Sure, if you're lazy you won't learn anything because you'll get the AI to do all the work for you. But if you're that lazy I imagine you wouldn't have even tried to learn programming without access to AI assistance, so you're still doing better here!
If you're curious and dedicated to self-education, LLM assistance is a gift that never stops giving. You have to learn HOW to learn with it first, but once you've figured that out you can really fly with it.
