Really interesting. I have been making videos for a couple years (I review movies. Link is in my profile).I don't want to make it a full time job but even at my much, much smaller scale I see the analytics pushing me to review certain genres of films because those films get more views.

If I was trying to make money from it, I would certainly be tempted to pivot into only reviewing a specific genre. So it is no wonder that larger channels end up doing so much clickbait stuff: whatever pays the bills.
