I remember someone trying to justify college over self-educating (quality varying all the way from coursera to Wikipedia to YouTube to Facebook): you just don’t learn the same way anywhere else. Being with your peers, having your ideas cross examined in real-time and having direct and personal feedback is invaluable.
I think the same applies to wfh. Yes it is fun, yes I like that I avoid commute, but I’ve also become a shell of what I used to be (remember I wasn’t the most social guy in the first place).
I am looking forward to going back to office and enjoying the hum of work around me.
