Before ML Twitter there was the ML Facebook, but that fell apart after Bengio’s comments under a LeCun’s post magically disappeared, given they could be seen as a criticism of Facebook’s ML.

Twitter ML lived by the trust into the Twitter moderation team to not do anything like that. Not that the old moderation team is gone and the new one showed itself to happily kick major personalities on a whim, this is not the case.

DAIR and the old Twitter ML are already over on Mastodon, along with some academics arriving there too. LeCun, Sam Altman and Bengio will likely have their isolated instances and a lot of de-federation drama will likely happen, but I am not seeing a neutral middle ground that would fit all of them right now, nor emerging in close future.

Given that Paul Graham is now on Mastodon (he would be the guy to throw into acceleration any startup credibly able to replace Twitter within 5 years), I say that’s where it is going to go down.
