It's interesting how you used Taiwan and hackathons as example.
Despite their successes, I'll bet a decent amount of money that after Covid is over, many hackathons will resume to be in-person events.
In fact, think of this the other way, would people in Taiwan be happy if they hear they will be locked down forever? Of course not right? So people obviously derive some value from human interaction. And that value, as little as it is for some people, will very often translate over to working relationship.
>we didn't have spoken language for a very, very long time, and we interacted "just fine" without it insomuch as our entire ancestral history for a couple hundred million years survived to the point where homo sapiens could finally branch off and eventually figure out complex language. Same goes for writing. So, that's kind of the problem with naturalist arguments.
A simple counter-argument to all your examples: when something new comes along, they rarely fully replace what's there before, but merely augmented it or expanding the horizon. We didn't replace gestures and body languages with spoken language, and we didn't replace spoken language with written text. Technology will no doubt expand our interaction paradigm with new methods, but it won't fully eliminate the benefit of old ones.
