Is that a Kurt Vonnegut reference? If so, well played, sir!
Re the OP: I care about cubing. For me it's far more than a hobby, it's something I do because I like researching stuff, and it relaxes me, and a billion other reasons... but I don't have the time to dedicate to cubing that I wish I had. I first discovered cubing when I was a student, but there were nowhere NEAR the resources there are now. I found some algs, and got better, but then for ten years I just solved a cube occasionally, in a minute or so.
Then one day I stumbled upon the wealth of YouTube videos about cubing, that simply didn't exist a few years ago.
So here's my point - I think the accessibility of cubing means that more people will take it up. Obviously. Even if the attrition rate were the same as it was 10 years ago (let's say 70% continue cubing), due to the volume of new cubers, more will stop.
Also, again due to accessibility, you don't have to go out of your way to find out how to solve a cube. I think anyone could be at least sub-40 now, which simply wasn't true when I started cubing - there was no such thing as finger-tricks, or anything like that. The kind of people who would spend 3 hours reading a text-only tutorial about solving the cube (me) aren't the kind of people who forget this information lightly. The kind of people who want all of their information in bite-size, snappy, 5 minute YouTube videos are less likely to retain the information. It just doesn't take the same level of dedication.
If I'd had the same resources available to me that there are today, I'd still love cubing just as much, I'd just have spent many hours studying RLS or COLL, or WV, or ZBLL, or **(insert obscure method here)**. In many ways, I wish I'd had a combination of the time I had when I was a student, and the resources I have today. But I don't.
I don't take cubing
seriously, I just love doing it. I hope I always will!
