The thing that stands out to me looking back over a few decades is how much of consumer/public computing is exploring the latest novel thing and companies trying to cash in on it. Multimedia was the buzzword aeons ago, but was a gradual thing with increasing color depth and resolution, video, 3D rendering, storage capabilities for local playback, sound going from basic built in speaker beeps to surround and spatial processing. Similar with the internet from modems to broadband to being almost ubiquitously available on mobile. Or stereoscopic 3D, or VR, or touchscreens, or various input devices.

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.
