We are obviously talking about the same thing, and nothing I said about the PP is novel.
I very specifically did not say that PP analyses were dead on arrival, or that problems with PP thinking were dispositive. I said rather that it is not enough to simply invoke the PP in policy debates; that rhetorical habit has bad outcomes. Again: the idea is not that "precaution" is bad. It's that you can't mechanically shift the burden of proof to anything "new" and assign a lower risk to the status quo by default --- you have to make that argument on the merits.
There's a good Cass Sunstein thing about the PP if you're interested in understanding critiques of it:

Not quite - it is true that you cannot assign a lower risk to the status quo by default, but the burden of proof is on the new intervention to prove that it's safe, not on detractors to prove that it isn't.
In other words, if the world is functioning today, you need to prove that your intervention won't cause ruin, no matter how small the chance or how big the upside.
