It seems to be a common thing. I gave up on /r/futurology and /r/technology over on Reddit long ago because it was filled with an endless stream of links to cool new things with comment sections filled with nothing but negativity about those cool new things. Even /r/singularity is drifting that way. And so it is here on the Fediverse too, the various "technology" communities are attracting a similar userbase.

Sure, not everything pans out. But that's no excuse for making all of these communities into reflections of /r/nothingeverhappens. Technology does change, sometimes in revolutionary ways. It'd be nice if there was a community that was more upbeat about that.
