Speaking of dwindling intelligence, this video seems pretty scary.
Yep, that seems to be of a few trends coming from teachers lately.
I firmly blame tech on this and removing writing (I'm one of those that think cursive (or atleast way that it teaches kids to think of letters and words) in general (or at least mitigating how much time is spent on it) with regard to reading. And the lack of reading has also led to the lack of actual quality entertainment as well. On average that is. I can lay blame squarely on the parents as well as the teachers, who gets it worse, that does depend on the nuance of the situation.
The problem is that most people want to "go go go" on the tech and we aren't wired that way and we don't change our wiring nearly as quickly as tech evolves. Nowhere near it. As much as I do like tech and can see it's potential, I also came during a time that tech wasn't there, one had to know the analog way to get anything done and so far, just about every phase of it's evolution, I had to deal with in some capacity. A lot of these kids (and perhaps some users on here (millennial and younger)) have really only known the tech. Don't get me wrong, there were still electronics, still had game consoles (Atari, this was from the 70s and 80s, NES etc), but it was nowhere near the center of attention that it is now.
I'm more of an old school luddite. I don't mind tech, it's how it's implemented that's going to get us into trouble. Not just "AI", but even tech that has been around 30-40 yrs, but is so abstracted away from the end user now, we have kids that don't even know file trees.
