I know there has been a lot of ink spilled trying to persuade that Technology can't solve our deeper problems and Technologists are too optimistic about having real-world impact etc. etc.
But I think community notes (the model, not necessarily the specific implementation of one company or another) is one of those algorithms that truly solve a messy messy sticky problem.
Fact-checking and other "Big J Journalist" attempts to suppress "misinformation" is a very broken model.
1) It leads to less and less trust in the fact checkers which drives more people to fringe outlets etc.
2) They also are in fact quite biased (as are all humans, but it's less important if your electrician has socialist/MAGA/Libertarian biases)
3) The absolute firehose of online content means fact checkers/media etc. can't actually fact check everything and end up fact checking old fake news while the new stuff is spreading
The community notes model is inherently more democratic, decentralized and actually fair. and this is the big one it works! unlike many of the other "tech will save us" (e.g. web3 ideas) It is extremely effective and even-handed.
I recommend reading the Birdwatch paper [0], it's quite heartening and I'm happy more tech companies are moving in that direction
