I agree with some qualifiers. I think some of us went all out with 'its just better' due to incessant onslaught of corporate propaganda telling me spending 2 hours in traffic is akin to meditation and 'me' time. Those ridiculous statements caused a lot of people to go into messaging overdrive that, arguably, lacked nuance.
Personally, I can attest that in person has some advantages over remote ( training comes to mind ), but I agree with the gist of the article that a lot depends on the audience ( some people don't need constant hand-holding ). And that is just two facets without touching the fact that not all jobs can be remote ( although a lot could be ) and some industries are ran by, well, old people who only know of one way to do things.
Is it harder? It can be. My team was fine, but some of us were already fighting for off-site schedule pre-pandemic.
After pandemic started, I made an obvious prediction that we will see some differentiation in companies ( full remote, hybrid, in person ). Workforce already voted for what they want ( remote jobs see 3-4 times the applicants ), but it is a larger cultural shift and companies would love to keep remote as a carrot for 'top performers'.
