It mostly just confirms my biases.

Part 1 - ad dominated businesses cause platforms to abuse customers in oblique ways
Part 2 - imo content and content rules are poorly organized because there's no hierarchy/composability/scarcity
Part 3 - bad content doesn't cost anything and it gets elevated because it costs nothing to upvote a car crash
Part 4 - people are especially bad when it costs them nothing to be bad
Part 5 - power to curate/moderate should be expensive to gain, exercise, and very limited in scope/effect

He hasn't written about his own solutions yet, but his hints are things that we're already familiar with:

• You get one account – that’s it. (In practice, this probably means he's going to KYC you)
• There is no “one” algorithm. (Great in theory ... in practice, I suspect most differences in algorithmic preferences, when the algorithm isn't optimized for the wrong things, are marginal ... i.e. we might want different condiments on a hotdog, but we're still at this hotdog stand for a hotdog)
• There are no community moderators, only sherpas (It's unclear what this means, which is why I suspect they think it's a solution to anything.)
• It’s all attribute tags (I've seen this tried many times, and while AI might fix the problems with it, it's usually chaos ... because at root, it comes from a rather naive wish for no information hierarchy to exist and a belief that somehow no opinion and preventing opinion is not itself an opinion ... and I think it's better to support primitives for hierarchy formation and just make it expensive and therefore self-organizing.)
• AI acts as a helper, NEVER as a creator (I suspect this mostly relates to preventing people asking dumb questions (which I don't think are that bad and are probably extant for good reason) and with the tagging part above.)
• A centralized platform ("My house has a toilet." Congrats bro.)
