I’m doing this now as I learn Unity and come back to C# after a couple decades away. It’s great for helping with syntax and reminding you of libraries, also with debugging steps as you mention. I haven’t had it full on hallucinate, but it has given me suggestions that fail to do the thing I specifically asked it for. I also went down a couple rabbit holes following its suggestions to later realize there was a much simpler answer that it didn’t tell me about. All in all, I’d still highly recommend it for my situation and OPs. If you’re able to follow the logic and point out the flaws, it’s a hell of a lot faster than googling or following tutorials.
What I didn’t realize about Columbo until watching it last year is that every episode is basically a full movie. There’s no connection between each episode, Columbo himself is the only recurring character. Each episode is an hour 10 to an hour 40 long. Also, it’s by FAR the best production and acting on TV in that era. It’s legitimately like almost 70 individual films.
