maybe... but back when I had time to actually listen to a few podcasts, I had no trouble finding better ones that did not devolve into this shitty format
Through recommendations of other users. A list of things I used to listen to at some point:
My Favorite Murder
The NoSleep Podcast
Welcome to Night Vale
Limetown
EOS 10
A Problem Squared
They're all close to 100% scripted and all but the first and the last one are fictional stories. So they're more like an audiobook than anything, except they're created with this form factor in mind, rather than just being a book read out loud.
Plenty of good podcasts, but they are either 100% scripted to stay on topic, or they have the good sense to edit down the improv tangential rambles so that the podcast stays on topic.
Unsurprisingly it tends to be older (35+) people with some kind of professional experience putting out the better stuff. The 20-something dudebro postcasts where they just wing it the whole time are awful.
40 minute podcast about [subjext] is 10 minutes of actual content, 30 minutes of riffing, going off on tangents, taking about their other podcasts, sponsors, talking about their next podcasts, talking about each other, their day, etc…
