I have been looking across various Lemmy instances and I recall seeing one or two that was cyberpunk-based or technology-focused in their local streams, but far too many have the "smug American Liberal" [1] style comments that made me leave Reddit [2].
Simply spinning up another community is not a quick fix either. Concern trolling means Centrist communities simply do not last, as they eventually get overrun by extremists of one kind of another. It's far, far too easy to take a complex argument and have it dishonestly re-interpreted in a negative way as a a one line meme in public communities. Weeding these people out is far more of a challenge than banning violent remarks, racists and child abusers, as well-meaning people will inevitably misunderstand.
The solution to this is small private communities and group chats with people you trust, personally. You won't get the hit from having constant content to consume, but it's not as bad for you; getting in the door is the real problem.

I have found communities that cultivate for good discourse seem to end up the most balanced, but also attract lots of enemies.
