The evolutionary pressure selecting for general intelligence (to the extent that general intelligence exists) breaks once a species develops language.

And a logical corollary of this hypothesis is that we are only just smart enough, on average, to be capable of horizontal transfer of memes. Once language and culture arrived (note specialized usage of term ‚culture’), we didn’t need to get any smarter: we could „borrow” from one another. Therefore we’re only just smart enough to do this.
