Hot take (an I doing this right?): If you want to kickstart a new social network *right now*, make ML the distinguishing factor; both gimmick and potential killer feature.

1/

You've seen GPT-3's hype/virality on Twitter. Make it so that, in this new network, each account gets a shadow GPT account constantly fine tuned/prompted by the user's posts.

2/

It seems this could be fun: people could easily share their doppelgänger's utterances if interesting, or even "endorse" them when they agree with them 100%. That's labelling.

3/

Once people see that their use of the network improves their doppelgänger, things could get even more fun -- and further applications open up. The doppelgänger might become a good personalized writing assistant, to begin with.

4/

People should be able to choose whether the doppelgänger keeps running when they stop using the network. The default should be it doesn't; but users could opt in to get an insta-memorial if they don't find that creepy.

5/5 (for now?).
