You're perfectly within your right not to be a part of this group. I'm not trying to force you to take on a label or view that doesn't correspond to your experience. There's room for a plurality of explanations.
I'd be happy to read your experience if you're willing to share :)
My experience with work friends is that companies that foster social environments will have more people who are closer together. My first SDE job was at a medium size company that didn’t pay very well but it was a lot of fun. Bi-yearly all hands meet ups at a resort, tons of office happy hours, monthly outings within your own city. I made good friends there.
Then, when I moved to Amazon for the higher paying job, they have such a soul draining culture that it’s impossible to be very social. You’re more worried about doing better than your peers than you are working with them to build a better product.
My current job is completely remote so there’s no social aspect.
So, I disagree with your sentiment. I don’t think people want to be less social. Sure, maybe people are becoming less social in general, but I think overall it’s just tech companies are less likely to harbor good social environments.
