Nobody is "selecting." His point is that if it is highly advantageous to "look at and manipulate things on screens," within the population genes that makes individuals better-adapted for this behaviour will be favourable/selected for. It's just Biology 101.

They'll only be selected for if it affects their reproductive success, no? The problems we're discussing usually only affect people later in life, after they've conceived, so I don't see how could it have any significant impact in the natural selection process.

Bingo. Without reproduction pressure it doesn't matter either way.

His point doesn't make sense...
