Re: Loss of human contact
It's almost as if people are not all identical, and generalizations about them are suspect.
I've been working from home for over twenty years. I've worked remotely from my teams for most of my career - about 5/6th of it.
I get plenty of human interaction: In person from family, neighbors, shopkeepers, doctors, strangers I pass on the street; by phone, text, and email from family and friends; many times a day from my co-workers by various means. I have daily calls with members of two of my teams, and weekly calls with others, and ad hoc calls with all sorts of folks. I get quite a bit of work email, which I genuinely enjoy.1
I used to have face-to-face meetings with some of my teams once a year or so, and I did like that, even if (indeed, partly because) it involved international travel. But do I need it? No, I do not.
I'm sure there are many people who work best in a group setting. That may be true of most people. But people are adaptable, and I have yet to see any reliable evidence that a broad shift to working from home will have the dire consequences some are predicting.
1I realize this is unusual, but I'm a compulsive reader. Two of my degrees are in writing.
