Glad to hear you are solid! I've had some friends who got 'old' unrealistically quickly and so I feel the need to push back a bit when I see posts that remind me.
I'm with you regarding the social space though. I don't understand why entertainment appears to consistently trend toward requiring less conscious thought.
The way I see it we've gone from Physical Experience > Word of Mouth / Live Physical Performance > Books / Woodcuts > Newspapers / Pamphlets / Pulp Novels > Radio > Television > Modern Social Media. To be complete, I'd add a branch from Newspapers... > Telegraphy > Telephony > Usenet / BBS > Non-Walled Garden Internet but that is another story and not the mainstream.
The early steps all exhibit ?clear? trade-offs (more reliable information storage and dissemination at the expense of shallower engagement with the information being transferred), but the later stages appear to be reaching the limit of what we can consciously process.
I feel that at some point soon (if not already), the volume of information that can be received will outstrip conscious processing ability. This has a massively negative side effect of limiting human agency which seriously disturbs me.
I don't think the blame is entirely on social media however and because of reasons stated above, suspect the current state of affairs has been brewing at least as long as network television has existed. Possibly into the preceding era of disposable print. Thus, I don't put the problem into a 'kids these days' frame but more of a 'everyone I have known throughout my life' frame.
