We've designed communication systems that are optimized for instant gratification, engagement, getting the dopamine hit of seeing things you agree with or angry at, and rapidly moving to the next. That's not speech, that's a designed system of attention seeking, all with the primary objective of getting eyeballs on advertisements and content primarily.
We've designed communication platforms that cause us to cease seeing each other as human beings, and instead condensed thoughts and memes that are simply repeated to conform and get reinforced for a quick natural drug.
I do not think we should control the discourse or have structural control over what's right or wrong to say or think; that would be absurdly dystopian.
I do think we need to change our systems to incentivize human context around that speech, and reinforce our own humanity in how we read and respond to it.
I think it's possible to design better platforms that don't bring out the worst in society, and that we should do so.
