It's absolutely insane to me how bad the user experience is with video nowadays, even video that's not encumbered by DRM or complex JavaScript clients.
Phones are dominant now and have passed the PC generation by - in number, not capability. The concept of copy/paste/save for arbitrary data lives on for the non-tech masses only in the form of screenshots and screen recording features.
Adolescence is a very good word to encompass it, lots of awkward experiments trying to make the latest thing stick along with some of them getting discarded along the way when we grow out of them, they turn out not to be (broadly) useful or fashion moves on. What I wonder about is if the personal computer has hit maturity now and we're past that experimental phase, for most people it's an appliance. Obviously you can still get PCs and treat them as a workstation to dive into whatever you're enthusiastic about but you need to specifically go out and pursue that, where the ecosystem might be lacking is a bridge between the device most have as their personal computer (phone/tablet) and something that'll introduce them to other areas.
