I'll come at it from another angle. Some of the most popular podcasts (and YouTubers) produce hours of long-form video (an acceptable format) daily. Without naming names, some of those convey less information in 2-3 hours of video than some short form creators do in 2-3 minutes.

The medium influences the message, but the channel still matters.

(And some messengers, especially public intellectuals, are not doing the long form video/audio at all. One prominent TikTok poster has a $$$$$ job as a public intellectual and outside of short form, the other options to consume his content involve $$$ subscriptions or $$$$ in-person events. I'll take his 5-minute videos over those alternatives.)

Separately, I am chuckling at people saying TikTok is "all X" or "nothing but Y" or "overrun with Z." Do people still not know that statements like these are confessions?
