Neat! It’s not so much “forgetting” as it is similar tasks that require similar regions of the brain are more likely to trigger automatic reflexes. Social apps dont have many of those reflexes sonce social media doesn’t really exist offline, but things like CAD and ClipStudio/Photoshop/Visual Studio all have real world analogues and thus the habits you form from spending 16 hrs a day steeping in that system/mentality/carries over to similar tasks extremely easily.

The neurology of habis is absolutely fascinating btw, if you ever want to go on a wiki rabit hole I can really recommend that one as a cool one to go down for a few hours.
