meta is not here to promote open networks. They will do more harm than good. If you want to learn more about how google achieved it with the XMPP you can read the story here https://ploum.net/2023-06-23-how-to-kill-decentralised-networks.html written by one of the core developers.
I don’t think that accessibility in AI somehow correlates with the intelligence of the subjects using it. It can actually work in the completely opposite way where people blindly trust it or people get used to using it in a degree that they’re unable to do anything without the help from the technology. Like people who are unable to navigate 2 blocks from their house if they don’t use google maps navigation even though they do the same route every day.
