There is a recent news about elephants evolving to have no tusks... Something that is happening in a relatively short time span. I will no wonder if our modern trends (consuming anything to get pleasure and short-term rewards) will affect our brain size in a similar time span.

That was very much guided evolution though - elephants without tusks get spared, the others get killed for the tusks. There’s nothing like that happening with humans at a population scale, outside the realm of conspiracy theories

Are you more, or less likely to breed the more social media you consume?

If 90% of the people that use social media were culled every 2 years, and only the remaining survived enough to reproduce, we'd (maybe) see some accelerated evolution/correlation in a generation or two, right? (extremely improbable as you're not eliminating a specific physical trait, like in the elephant's case)
