There's a lot of YouTubers that started doing big videos like that and i just don't have the time to watch something like that and give it all my attention. Same with caddicarus, used to watch both of these a lot but since they started having massively long videos i just haven't bothered with them in ages
You definitely don't have to watch it all in one go. I usually just watch however much of it I want to watch that day and then send myself a time stamped link to pick it back up whenever I have the time and interest again
Of course if you're just not interested that's totally fair
At that point, you're basically just listening to podcasts. Leaning into it might be a good choice, since there's no visual element that gets lost when listening to podcasts, as compared to YouTube videos.
I would guess 80% of the people who watch these aren't actually watching them. Hell, background play is the real reason I pay for YouTube Premium. Not having to worry about ads is a nice bonus.
