Agreed. It's very much dependent on managers shaping corporate culture to foster effective communication habits, but once established, it very much helps productivity. I work with several teams in any given week and I find myself most productive when we use a private channel for dedicated discussion (which I can scan through later very quickly as a form of documentation), while the few meetings I have are dragged out, ineffective, and extremely inefficient since they bottleneck communication to a single speaker at any given time, preventing parallel discussion in separate threads. Also in a meeting I can't just turn off my ears and look up something to check and if needed ask questions, I have to keep my attention on the speaker, which harms feedback and discussion even more.
