If you had received one of these podcasts, say 3-5 years ago, I guarantee you wouldn't be able to tell it's AI generated. And I'm willing to bet it's valid for 90%+ of the people here, even those heavily involved in the field. The quality of the voices, the mimicking of umms, and ahhs, the subtle speaking over each other, they really are extremely impressive.
If you want you can do a test with people that haven't heard about the tech. Have it generate something you know they'll enjoy, maybe 2-3 min long, and have them listen to it without knowing it's AI generated. Ask them about the subject, and see if anyone mentions anything about being fake. You'll be surprised.

You would however be able to tell that it was extremely obnoxious and bland, and without the novelty of the technical trick, you would not be listening to it.
I strongly doubt that you're gonna be listening to this stuff recreationally once the novelty wears off, but if I'm wrong and you actually enjoy listening to two robots pretend to be excited about your documents and webpages long term, then have fun with that I guess.
