Substituting one form of media for another does not improve the hypothetical situation at all, giving a senior nothing to do all day except talk to a spreadsheet is not a solution to that senior being lonely, it is a false dichotomy. Far lower tech solutions can be (and are) used. In my locale we have volunteer schoolchildren active in the community, as far as I know that's quite common, and even half an hour biweekly with a fake grandkid is many orders of magnitude healthier and more meaningful than swapping out their TV for this generation's take on Fox News.

It goes without saying all these tools are still largely in their pre-advertising state, it won't last.
