I think this is interesting and come from a like background as you. Building machines and discovering our router had wifi on a Sony PSP.
Some thoughts:
1: Boomers and Gen X kinda screwed later generations with incredibly awful computer education in schools. Most schools are basically marketing firms for Google and Microsoft Office. Kids are just not taught the basics at all and instead are handed endless document tasks that are absolutely meaningless to real life.
2: One can argue that all of what you define as 'tech skills' are actually just legacy thought processes that have gone by the wayside. Folder structures are often silly on modern devices with great search. Startup sequences are unneeded to be known because their modern hardware solves it's own problems when things go wrong (ChromeOS for example can just re-image and restore files/settings automatically upon boot failure). They know how to type with their thumbs because the full size keyboard is not relevant and once again, schools don't teach it. Microsoft will gladly have GPT 4.0 write a macro faster than you could.
3: I would also bet that later generations are better at some things. Notably handling the social web, personal image, and expecting to deal with scams and fraud. Our generation got thrown head first into a world where everything is there always. Where your past follows you. They grew up with it, it is native. They know to be more careful in sharing. Their bullies sit down at their dinner tables and on their nightstand because the internet and social networks exist after school hours. General smartphone use skills are likely better. Gen Z is also, according to other reports, less likely to smoke or drink and generally more willing to make stable life choices.
It's easily to point the finger at a next generation but I think
A: The problem tends to be the prior generation's fault. It is wild that so many generations will say 'kids these days' but it is their kids.
B: The lens through which the generation is judged is not actually fair. I would also note this: The generation before us would argue that we don't know how to drive stick, read an analog clock, or balance a checkbook. The world moved on.
