This will greatly enhance the intelligence of future generations and make education accessible to almost everyone on earth at a similar high level.

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.

If large companies and influential people move to Mastodon [...] and no ads.

large companies and influential people are in the commercial platforms because of the ads. There is literally no reason for them to move in a place without ads.

while I would say I belong to the dark-theme cult, there are some applications/websites that I cannot get used to them in dark mode. Like github or slack for example in which everything else than they light theme looks strange in my eyes.

meta (threads) will not support fediverse already. They said they will do in some later version. So for the completely practical part, you don't need to do anything right now.

in this case we don't talk about users who want to block users of another instance. The problem is not the users of meta. The problem is meta itself and all the problems it will bring to the federated network. Whoever cannot see that their intentions are not to promote federated networks but to exploit and extinguish them, is just naive.

Am I just misunderstanding this?

yes

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.

you missed the point where the open source devs were in a constant race to adapt to all the google-"innovations" and actually troubleshoot on them which ends up demotivating

I’m a software engineer

if you're a software engineer you should had known to make constructive comments and also most importantly realise that you are on a Non-commercial open source one-man-project. Your attitude is disgusting and you sound like the guys that nobody wants to work with. Nobody forces you to be here and you're welcome to go and please take your cancer with you on your way out.
