These things are so new, the effects of this are still completely unclear. You may ultimately be right in saying "decline" but that word still feels premature because objectively we don't know.
Take a look at human history and consider how often we have behaved in antisocially as we harassed, harmed, or otherwise slaughtered each other by the hundreds of millions. It's not as if we're some ideal model that would be bad for future generations to completely deviate from.
Therefore my hypothesis is that it's equally possible something so dramatic and counterintuitive as the changes we see these days may actually be necessary to create a world we've only dreamed to achieve for millennia.
