What I think would be nice is if there we tools that better allowed us to create "social gardens" on platforms like Twitter, platforms that allowed us to better cultivate the topics we care about while allowing us to keep out some stray topic from someone who we otherwise follow because of something entirely different.
There is of course the argument that this could lead to even worse echo chambers, but for me the more pressing concern is preserving my mental health and disengaging entirely from the political conversation. Doesn't matter what side of the aisle they're on, Twitter pundits are unhinged and I want to stay out of the twisted world they inhabit. Meanwhile, I find that Twitter is actually a really useful platform if you carefully curate the people you follow. There are some powerful ideas if you know where to look.
Ah, but who am I kidding, people would much rather possess a nuke than a garden.
