I think the lies on the internet thing will have to defeat itself. I remember being led astray by internet “wisdom” back in the first dot com bubble. Then I went and tried to apply that knowledge IRL. I don’t remember any single particular example, but I remember feeling downright embarrassed for believing something off the internet. I then learned to always take anything from the internet with hefty doses of salt rocks.
Of course - we are all responsible for ourselves. The problem is that critical thinking is not taught in schools, and children grow up without it by the millions. A problem doesn't "defeat itself" and people who have trouble thinking critically cause problems for those who can do it naturally. Saying that there is nothing to worry about from having tens of millions of people believe lies, or saying "that problem will not receive a solution from ME or ANYONE I know!" (basically, "will have to defeat itself") is going backwards.
The world, the whole world, has a problem with fake information on the internet right now. The answer is not "oh well, too bad" and the answer is not "I'm not worried".
