I don’t know how true that is... you have tools today with the UX of then (vim, web 1.0 websites) and they’re both functional, useful, and not really that different from their modern equivalent. Software-wise, its hard to say that much has changed.
The main difference is uaage between early web and modern is web-apps (not significantly different from desktop apps) and the amount of sheer content to be found. Perhaps the centralized usage of social media too, but their usage is probably unsurprising (more surprising is how much personal info people feel fine giving away)
Hardware has become radicaly different, but somewhat in an expected way: everything got more dense. The only major shift in thinking there might be touchscreens, and google/gps available anytime anywhere, but neither are particularly surprising.
After GUIs became a major thing, I would argue most of our UX went stagnant. You could pull out a 1994 pc today and have no issue using it, and someone from 1994 would likeky have little trouble with windows 10, or even an iphone (after getting past the touchscreen).
Things got faster and smaller, but not different. Certainly not the difference of something actually “savage” (like a stone tied to a stick) to something truly “modern” (like a powerdrill), that would require a totally different mindset to use
