I agree. I have been fully remote for a bit over 2 years, and I myself feel a change. In the early days I had a managerial role so I felt the need to visit office and deal with employees, colleagues and customers. Office is 5 miles so not too far, I just avoid going as my family health issues may require my intervention. Now that I am an IC, and the health issues are not sorted, my visits have reduced, and I think it is slowly changing me for the worse - in terms of discipline, social interactions and even productivity which you think would be higher from home. Thankfully though I am starting to recognize some of the patterns and working to fix them but you can fix productivity, you can not fix lack of socialization.
