The effect is mostly from the total number of computer users increasing.

That is, the total number of "tech-savvy" users keeps increasing (https://datausa.io/profile/cip/computer-science-110701) but the number of "non-tech-savvy" computer users has absolutely exploded (https://semiconalpha.substack.com/p/global-semiconductor-sales-increase) (that actually undercounts computers since every dollar in 2020 buys you much more computer power than a dollar in 1987)

You had to pass a nerd gauntlet just to get online in the 80's or 90's that meant that everyone you met online had also passed that gauntlet and was tech savvy. Even if you looked in the social usenet groups, a lot of non-technical users were just filtered out. So it looked like everyone was tech savvy but that's because we were sampling a tiny, tech-savvy portion of the population.

Now anyone can get online. The tech savvy gen-zers are still there but their hidden in a sea of non-technical users. If you go to places like Github or Hackernews (or even more specifically technical fora), you'll find plenty of enthusiastic young people poking at technology and trying to make it better. They no longer have to mess around with autoexec.bat and config.sys to get their mouse working but they can (and do) get a bunch of Jupyter notebooks and start playing around with Tensorflow.

A great modern example of this is 3-D printing. Modern 3-D printers suck. If you're a big company you can get super expensive 3-D printers that take up giant rooms and need a team of experts to run. If you're a home user you can get a cheap FDM printer but you best be prepared to tinker with it. The first thing most people do with their Ender is print mods for their Ender. Bambu Labs is a big improvement but they also attract a lot of users who at least could mod their printer https://forum.bambulab.com/c/bambu-lab-x1-series/user-mods/19

Some day we may have little boxes like in "Diamond Age". Kids in the future may not even know about crap like bed adhesion and stringing and they'll concentrate on whatever the new problems are revealed once the current ones are taken care of.
