Formula for such things:
1) Notice some seeming coincidences
2) Recognize a trend
3) Accumulate 2-5 factual points about the trend
4) Mix in 2-5 points from one or more co-morbid trends
5) Come up with a random explanation based on personal beliefs
6) Attach 4-10 hypothetical points based on random explanation
I think in this case they've hit on a real trend which is the Flynn Effect (the rise of IQ across generations) and so the first part is really classic gifted traits being seen in a wider field of the population thanks to nutrition, etc. The co-morbid trends are the Gen-Y/Information Age sense of entitlement plus the information age push towards global thinking.
Of course this is just my random explanation based on personal beliefs.
