Vhs came out in 76, blockbuster started in 85 (we went to video stores well before that when I was a kid), dvd in 95. I remember the sopranos making a joke about how dvd was barely taking off, they started in 99. Lets call it VHS had a run from 80 to 99, that's 19 years. The iphone launched in 2007, when did mobile become huge or inseprable from doing life (by force by so many apps), probbably in the pandemic.
I wouldn't say VHS was a blip. It was the recorded half video of media for almost 20 years.
I agree with the rest of what you said.
I'll say that the differences in the AI you're talking about today might be like the differences between VAX, PC JR, and the Lisa. All things before computing went main stream. I do think things go mainstream from tech a lot faster these days, people don't want to miss out.
I don't know where I'm going with this, I'm reading and replying to HN while watching the late night NFL game in an airport lounge.
