My personal experience has been that teams were not in close physical contact since about 1994. Basically since the internet became ubiquitous. In 1999 I was working in an office in Silicon Valley and realized that I never sat across the table from any of the people I was working with. Some were in other buildings around the campus. Some were in France. Some were in the field. Some were down the hall on the same floor, but if you wandered over to talk to them chances were they weren't in their cube. So I decided to move to Montana. COVID occurred 21 years later.
