Our chilhood was totally different than today's. Comparatively, our chilhood was pure and simple and we were brought up only with TV and atari as well as custom toys. Now, they are brought up with smartphones, tablets and social media accounts.

I didn't have computer until I was 16 - Still made it into IT :)
Confidence, no matter how unskilled they are in evaluating their abilities.
