You already answered your own question, nobody with the right mind would hype an AI coin where 90% of supply goes to either team or investors.
If you shill it the one who became rich is the team not you, while on meme coin decentralization of holders matters a lot.

Nobody gonna ape to a meme coin if there's wallet holding huge chunk of the coin. In short, nobody is trying to shill or hyped it up if they don't benefit from it.
