If it was vomit, it will be recognized quickly, AI or not, not an hour of listening for sure; yes, even if it was sent by a friend.
If a random podcaster says "I've proved that P=NP" I'd say "no you didn't", but if a math professor sends me that same link I'll keep listening to see where this goes. And I've definitely read texts making wild assertions that only at the end were revealed as hit pieces and/or propaganda.
In that case i would listen to all of it aswell, otherwise i can't give honest feedback.
