I'm excited by AI, but I've also tried using this specific one to generate a podcast based on one of my own blog posts and will only try again due to this product announcement rather than because I think the state of the art is already "there".

On the plus side, the speech is almost perfect; so good, that I sincerely hope the voices themselves are never fully under user control.

With regards to the actual summary of the content I gave them, I would say they are grade B: only mostly correct, they're still inventing things I didn't say and missing things I did say.

That's not to say humans don't make mistakes, I still consider this objectively impressive, that is able to reach even this level was SciFi when I was a kid — but why waste time on a grade-B podcast when the AAA-tier costs you as a consumer a 30 second advert?
