All I will say to add to this discussion is that I have been privileged to see some of this "new generation" in the work place, as doctors, scientists and engineers and I have nothing but compliments to give (based on my experience). People working 60 hours a week (paid 40, exempt) and the desire to understand how things work, why they do not work, ...
Think of SpaceX, do you really think the young PhD and Master of Science employees are lazy? Maybe they don't have any interest in physical work or tinkering with cars or bikes, but their skills are amazing. And to reach that level they work hard. I know a lot of people who have spent a night in the office, or worked all night at home, including weekends.
We are making some major advances in pharmaceuticals and the young people with PhD in chemistry are part of it.
I don't see us going downhill at all.
Technology is a good thing when used right. There are always people who will misuse it (and I would bet it was the same when people invested knifes or anything else).
Years ago a 16 year old - on his own - beat the DVD encryption. That took a lot of hours spent patiently in front of a keyboard to reverse engineer what a team of people did.
When I grew up I did not car about cars or anything mechanical. But I was always in a book (no internet) learning all I could about math, electronics, physics and so on.
Adafruit sells a lot of kids to eager teenagers wanting to learn about electronics and uC programming. Lots of them spend a lot of time getting their design to work (programming and hardware).
I am not worried about the new generation. You can fixate on a few people, but overall we are going to be just fine.
