These are points that I have found to be true as well. In many organisations where remote work is not allowed I found there to be generally worse communication, masked by meetings that achieve very little other than giving people a false sense of "work being done".

There also seems to be a lack of properly planning tasks and as such this lack of planning is papered over with the sort of serendipitous spontaneous communication that happens when you have to walk over to someone and ask them what on earth is going on.

A focused remote worker can be orders of magnitude more productive than the typical office worker who is simply doing "busy work".
