Notebook LM is pretty interesting to play with. I like using it to summarize multiple articles on the same topic. It’s already gotten a lot better over the last year, but it would be nice if they would allow you to switch up the voices. I don’t think it will ever be as interesting as actual human conversation, but it’s still helpful.

I’ve found that there are positives and negatives with human podcasts. With human podcasts, you get personally, opinion, bias and a unique perspective on topics. Those can be good or bad. AI podcasts lack those things which can also be good or bad. I like it for studying a topic, but it’s not quite as captivating or interesting without human qualities.
