Socrates wasn't wrong. The adoption of new media should reflect a rational analysis of its benefits and drawbacks.

Writing enables us to store, transmit, and reflect upon information in ways that surpass speech. One negative consequence is that we get less practice in exercising memory, and we encounter more information than we could commit to memory in any case.

Social media enables us to get current information on the doings of people whose lives interest us. One negative consequence is that the information users encounter is subject to manipulation by those who dictate the content of the website, with the result that most users have reduced intellectual autonomy. What's more, much of the information presented is not relevant to users, which wastes much of the finite attention they possess. Data collected about users can be and is used to advance interests contrary to their own. Some of these issues are intrinsic to social media as a concept, others specific to the platforms that currently dominate.

Either way, it cannot reasonably be presumed that those opposed to the use of social media are simply Luddites.

Can you cite that exposure to written material has a negative impact on memory? It seems like an extraordinary claim.

One way to test it: there are significant numbers of muslims who as a matter of religious practise, fully commit the Quran to memory for recitation, this is one of the few modern traditions to use the old style of word-perfect oral memory. And there are plenty of "control" muslims from essentially the same backgrounds who don't bother. Comparing them might be interesting.

It isn't exposure to writing in itself that reduces remembering, but the difference in how literate people tend to behave, by relying more on "external storage" than their own memories. I first became aware of this possibility when I took a class in translating Homeric epic poetry, much of which has been shaped by its origin as an oral tradition. (For instance, it has been speculated that the many repetitive phrases the Homeric epics are aids to memory -- 'the swift-footed Achilles,' etc.)

It's well established that remembering is to some extent a skill. You can find sources with a cursory search. If you're interested in a longer treatment of the subject, "Moonwalking with Einstein" by a journalist named Josh Foer, who managed to win the largest memory competition in the US using mnemonics, is well worth the read.
