If you went back to the 90's and showed a concept video featuring pervasive personalization based on data mining, no-UI uis, and things that just work, people would see fever dreams at best and unwholesome value-destroying privacy-invading witchcraft at worst, the brand of which informed science fiction of the time.
I don't think the iPhone would have sold back then. But if you gave them the flashy stuff in this concept video, Microsoft would have been Google and Apple combined.
Oh yes. The hacker subculture, even parts of the tech industry in general at the time was dealing with things like the Clipper Chip, the V-Chip, and Operation Sundevil. There was a love of tech, but a good dose of distrust as well.
There was also a certain aesthetic to 90s tech. It needed to be obnoxious and tech-looking. Well, everything needed to be obnoxious & in-your-face in the 90s.
I'm pretty glad I don't have a house that yells "COOKING PERIOD IS OVER" at me while flashing the text in bright red letters on my TV when dinner is ready.
