I believe the premise of your argument is false, there are lots of people who aren’t capable of learning something. Not just because they refuse to learn but because there are genetic limitations. it’s scientifically proved by the bell curve of intelligence. There are just people who will not learn the same as you as you will not be able to learn as someone else unless you are a genius. For example I am dumb as removed about quantum physics but I perfectly know all the settings in a smartphone and there are people who are worse or are better doing the same.
I’m not saying people with less intelligence are bad people and geniuses are good people, I’m just saying everyone is different, and not just about intelligence, physical characteristics vary too, as for example I don’t believe you can play in the NBA and also not me. You got my point?

I have a hypothesis about it and its evolution isn’t as slow as the majority of people think, something that will happen in hundreds of years you know. I think 100 years could be enough for something to change, maybe it is just younger generations are already genetically adapted to new technology but as it advances the next generations will be even better adapted or less adapted as the way technology evolves. But take this with a big grain of salt because it’s just my hypothesis.
About people being dumb or no I said, not everyone is capable of the same things. All people are different, someone can be good at something but dumb at other things. Just as we are not playing in the NBA or being experts in quantum physics. I understand it is an extreme example but you can get the point.
