This is only me describing my personal taste, but:

Almost all video essays and podcasts I would rather just read. It takes half the time. Include pictures, diagrams, and animations if needed. But I can read much faster and retain much better reading than listening to someone talk. Listening at double speed is faster, but can be uncomfortable.

I can imagine some value in some other niches, like you’re saying, but the amount of slop and trash out there is too high for me, and the companies selling it are the worst.

Every time I see some parasocial YouTuber making That Face I just get irritated.
