Shows like John Oliver could go 20+ years easily. If he’s happy and making the exact show he wants to make, I don’t see why he wouldn’t keep going. Bill Maher is on season/year 21. And it really can’t be that expensive compared to their other tent poles.
It sounds like you might be misinformed - a YouTube Premium subscriber watching your YouTube videos is worth, IIRC, 5 to 10 times more than an ad supported view for the content creator. I know a number of content creators have indicated as much for years - I wish I could cite a specific WAN Show episode from Linus Tech Tips who I’m certain has talked about it many times.
