You are absolutely correct. Kids today know how to use high tech gadgets that someone else produced, but few understand the internals. In short, they are users, plain and simple. They are also not critical thinkers for the most part.
On the other hand, let’s not pretend that there was a surplus of geniuses in 1912 either.
A lot of people that were kids in 1912 went on to develop technology and weapons used in WWII.
My real point in responding to the post on this thread was to point out the degradation of education by design of some very bad people. Your mileage may vary. By design, our posterity is more vulnerable to survival issues following a disasters than the kids of 1912. That is not a function of growing technological advances. Rather, it is a sign of our failure to better prepare our children for self-reliance. Again, ymmv.
On the other hand, most kids today would be scared to feed chickens or even clean out a chicken roost.
