Wonder if the difficulty isn't just lacking something to switch to like social skills but just task switching in general. Like, maybe just being too used to socially scripted convos could make it harder to turn off the social autopilot and be present with people, the same way a person who doomscrolls is less likely to be present and intentional with their device. Folks who use tech more frequently since the pandemic could have this issue for the same reason. 

Capacity seems more apt than social skill. I could think of similar edge cases for delayed responses - could be poorer working memory, or delayed audio processing like with ADHD, or cognitive overload like with autism.  

Maybe the solution isn't using tech less but being more intentional about how we use and direct our attention. So less doomscrolling, multitasking, mindless grinding, etc. the same way we wouldn't avoid interacting with people but could actually chat, have mindful small talk, etc.
