As a former introverted kid, I never liked being forced into situations where I might have to actually talk to some other person, especially of the opposite sex.

But, I can look back and be grateful there were no smartphones to hide behind, otherwise there are some hang-ups I might never have gotten over.

As an introverted person, spending more time alone as a child was the last thing I needed. There were a lot of social skills that I didn't develop until my mid-to-late twenties that would have saved me a lot of grief if I had been pushed into developing them earlier in life.

Sorry but no. Even as an introvert, I can still recognize the problems that being able to escape into a smartphone during school would have caused me later in life.
