The Hivemind Complexity.
I say that because it is a collective process that exist in a large amount of online communities, Lemmy and the Fediverse being no different. People online are way too used to having thoughts of theirs being parroted. Then comes the constructs of all of these karma systems for people to vote said thoughts of and that creates a level of its own discourse that, people will say or do things for some validity based on that.
And anyone else who comes along that thinks or says different than the seeming majority, are scrutinized, bullied and branded to be moderated.
Everyone is just too used to being around others who agree with them.


Not really. It’s kinda like asking what will we ever do if something happens in outer space that’ll mean the end of our earth and all of the combined wealth of rich people can do anything to help it (they’ll hoard it all anyways and think they’ll see their money afterwards).
Things that have a beginning, have an end, that’s life in general. You live it. You do what you can in it, try not to be the most worst individual and whatnot. The sad part of it all is not being able to carry over everything you’ve learned and those you’ve known. Then again, it won’t matter at all in the next life you’ll be in because everyone you’ve known is long gone into their next journey wherever and whomever.
But as for the positive legacy? Well, the only way we’ll ever do that is if we’re in positions of power, have all the wealth or born well-known with unmatched charisma. It’s just a damn shame we live in a timeline where all of that is horribly misused and abused.
