We're not going to stop it because of the money involved and once we're dead, it won't matter anyway, might as well just enjoy life until you're done.
We're going to get AI'd to the max, whether or not we like it or not, might as well just go with it.
It sounds like something is worth worrying about if you foresee us being dead, presumably prematurely.
I don't think your LessWrong post is going to save us.
The only way it will stop is if the wealthy / powerful people feel threatened by it, properly threatened.
