Criticizing rationally acting rational actors on hn is discouraged because it is "low value" or "uncivil".

When the rationally acting rational actors are pressed for answers about how their vision of the world would work they tend to reply with either examples from science fiction space fantasy novels or something that is just a simple dictatorship.

In order to add to the conversation you should sprinkle some effusive praise about the AI/Crypto/Fintech/Quantum scam du jour (or criticism of Apple) into your comments to throw them off the scent.

Something like:

"Oh boy I really get what you're saying! Here at my quantum fintech startup we're using LLMs to turboencabulate novertrunnions. By the way did you know that safety regulations are written in blood and after years of working effectively the public may forget why they were implemented in the first place but the underlying issue will just return absent the regulation and a newer generation will just have to rediscover why the regulation was created and that's something we should avoid?"

The initial tease excites the techbro-- they start daydreaming about being a billionaire dictator of a mars colony and that floods their brain with pleasure hormones which lower their defenses.

This leaves a small, but existent, chance that you can hammer some reality into their antisocial brains.
