Arguably we already have, if you concentrate on intelligence rates since 1975: the reverse Flynn affect. Those who grew up about that time no longer had to generate their own entertainment through storytelling, make their own music, calculate things mentally: everyday they had music, entertainment pumped into their homes, a way to avoid athematic, etc. And now we're evening thinking a lot less in our jobs, not even practicing the skills we learnt. Intelligence is only going to decrease.
