I don't think this is a new feature of humanity. Consider the people you know who don't care to learn about, or pay attention to: Food (cooking, sourcing ingredients), cars, health care (e.g. what drugs do what and how; what makes your body+mind feel good or bad in the long term), electrical wiring, plumbing, "nature", etc. Computer technology just seems like another aspect of the world which many people are happy to ignore. Also... consider the number of professional computer programmers you know who don't read the readme+API dox but jump straight to stack overflow
Wow, I regard all of those to be interesting subjects, and consider that an adult should have at least a cursory knowledge of all of them. However, you are right, plenty of people just don't want to know anything about any of the above.
Consider this fact: 70% of the adult population of the United States is overweight or obese.¹ An uncharitable interpretation would be that 70% of adults in the United States cannot manage to feed themselves appropriately.
I have a cursory knowledge of how a car works but if there was a problem where it couldn't start and the problem wasn't that the battery is flat or out of fuel then I would have no idea what to check.
I also don't drive a car so this skill is mostly useless to me much like some people don't need any more computer skill than just being able to send emails and read websites.
