Anecdotally, it doesn't seem to be the case. For those who have their spouse and children (if they've reached that point), and in a WFH situation it's possible not to encounter a single other person in the day during the week, until running errands.

If you're living alone, then it's trivially possible not to socialize at all for days at a time (and beyond) - you now have to rearrange your life to meet people in your leisure time. You have to join meetups, sports, clubs, after working all day because work is devoid of watercooler talk, of idle chit-chat. And so is your home. The precedence of having made friends in formative years and keeping them helps, but they're busy too - you won't see them every day.

So now you're looking at spending real $ just to meet an adequate threshold of social time every week.
