Future

There's an interesting theory I've heard recently. It has been proven that in our modern society, intelligence and procreation share a negative correlation. Thus it naturally follows that more lesser quality genes (on average) will be passed onto the next generation.

Theoretically this should directly result in humans growing stupider over time. This effect has however been counterbalanced due to the much better environment modern humans are being nurtured in. Better food and education being major factors.

Essentially, humans are just wasting their potential.
