Steve's Law: No matter where you are on YouTube, you are never more than two clicks away from a Minecraft video.

Not necessarily true. The recommended videos are based on what you watch. I hardly ever get recommended Minecraft videos.

2 clicks away can be the following. If some channel you watch is subscribed to a Minecraft channel, you can get a Minecraft video by just looking at the channels profile. Not necessarily recommended videos.

Yep. It was tongue-in-cheek. More of a comment on th sheer number of Minecraft videos on YouTube.

My 9 year old daughter regularly watches "TheDiamondMinecart" on YouTube, who has 10.9 million subscribers. From the little I've seen, it looks like about 80% of his videos are Mincraft, 20% other games.

Yeah, we (if you are 30ish plus or minus) probably had TV shows and cartoons as shared reference points - this generation will have which Youtubers they watched as those reference points.

I don't know about that, there are so many more YouTube channels and videos, while there were few enough OTA channels and shows that there will be common experiences.

Everyone knows who Bugs Bunny is, and can probably share the memory of a few plot points of some iconic episodes.

A group of people 20 years from now talking about videos they watched on YouTube will have a hard time coming up with a channel that two of them remember watching, much less a particular video. Unless, of course, they play the stupid game of "no, I remember one that was funnier" and spend the time searching on their phones for that one video that will one-up the others while to playing the videos they have queued up...ugh. https://xkcd.com/920/

You're right that there will be a way higher number of reference points with varying degrees of awareness, but I'm pretty sure most kids know Stampycat, Evantube, etc..
