But its a bit besides the point. Presenting the information doesn't suddenly become a worthless endeavor because people's minds aren't changed by it. Having the conversation is enough.

I know you can't get someone you're debating on the internet to say you're right and yet, I have arguments on the internet anyway. Why? Because other people can read that debate and get information from it, but also because an argument had today can be a memory in the future when its relevant to that person and their experiences start to reflect your side of the debate. If the debate was never had, if no one bothered to explain it to them before just because their minds weren't changed in the moment, they'll be left just wondering why with no answer and maybe keep running into trouble with different ideas for why until finally learning.

Ironically I'm literally telling you to have long time preference with your internet debates and to think in terms of second and third order effects rather than primary effects alone lol.
