I was about to post something similar to Luciano's.

Robots or electronics, or something scientific in general?
Are they supposed to be something good for the children for their future if they start learning about them today?

Who knows, may be these will turn out be something bad in the future.
Who can suggest to be a scientist rather then being a singer, or a soccer player, or a ballerina, or F1 racer?

Who can prove that one is better then the other? Based on what criteria?

As long as people make choices, No One Can.
