I don't think that this leap of efficiency in "exploiting human psychology" is anything different from propaganda/marketing leaps of previous aeons. Reading the books of the past, they felt equally exploitative and novel back then.

We've coped with that, our descendants will cope with social networks we've created, as well. Attention management and rapid critical thinking would become as crucial mental capacities as IQ and EQ are today.

If, of course, smart people acquiring these skills over the next generations are still going to have descendants and the volume is significant enough, because typical "exploited" subjects are going to, you bet.
