I'm in the top 10% with my IQ, but my social IQ is very low. I also have ADHD, so I hated reading, or studying. Now I know that that was because I couldn't keep my focus. There was also no need for me to study, because I was just paying attention in class, and that was good enough to pass all my exams. The classes that were a little more challenging, those were the classes that I had to study a little for.
So being smart isn't everything. I was a difficult child, and I only learn what I really want to learn, what interests me. If I'm not interested, I'm really not interested, and then you'll never be able to teach me...
So in the end, I studied mechanics, and welding. Working with my hands was fun, and then I didn't have to study hard.
I still wonder what would have happened if I indeed had studied engineering. I think I would have loved it, and been pretty good at it. But that meant a lot of studying, and nobody was there to help me...
So let's not just look at intelligence. You need to look at the whole package. I think everyone is good at something. We don't all need to study hard. Especially now, when AI will be our brains. Better to learn a trade if you want to have a job in the future...
But don't be too stupid either, because robots will do our low skill jobs as well, like flipping a burger, driving a truck, cleaning, etc...
But we can't all be welders and plumbers... So what's our future? Time will tell... It ain't gonna be much...
