Even setting that aside, your premise doesn’t hold: you can’t “learn from experience” by watching others. The whole point of the phrase is that you have to do it yourself to learn.
That's not enough. Repeating the same stupid ideas again and again and again without learning from past failures is not a viable approach.
The only stupid thing is following this absurd "argument" from the article. Kids, stoves. Seriously, what the fuck? Giving up on things after first negative experience is no way to live a life - literally, you would not survive to adulthood if you followed that brilliant idea.
At some points you have to stop trying stupid things.
Here the stupid idea is thinking education is a solo activity while in truth it's a social one. A 50's multiple choice quiz on papers is the same as a quiz on computers. It's a very small part of what learning is about.
