I can get behind the idea that remote work is not as effective especially when forming a new team or assimilating new team members. However the thing that the ‘remote work is bad’ crowd get wrong is the distribution of collaborative work and deep individual work.
My experience is that in person collaborative synchronization is needed far less than even once a week. In person touch points with a white board and plenty of getting to know each other as humans time is super valuable… and in my opinion 2-4 times a year in needed, not 3-5 days per week.
