Roon, an OpenAI employee, labels Gary Marcus chronically wrong and a slimy person, prompting Marcus to cite Paul Graham’s hierarchy of disagreement and link to a GitHub study

Theo shares screenshots highlighting ad hominem attacks in the thread.

I love that this post, my most foulmouthed ever, has gotten 100k views.

You want to know why it has spread?

Simple. Because a lot of people have become really fed up with OpenAI.

Gary MarcusGary Marcus@GaryMarcus

Fuck this OpenAI employee, seriously fuck him. Also read this quantitative study, which I had nothing to do with, that says my technical predictions have bee largely correct. https://github.com/davegoldblatt/marcus-claims-dataset I should not have to put up with this level of unhinged hostility, simply for defending views that have frequently been challenging to his company. Nor should I have to put up with him neither giving evidence nor allowing me to respond. This man appears to be both a coward and a liar, with only insults, literally a bottom feeder in @Paulg’s pyramid of argumentation. That this empty slander is all he has got is perhaps a sign of how desperate OpenAI has become.

OpenAI’s “Roon” is officially a chicken, just as I thought. And just like his boss (who has also ducked debates with me).

If either actually thought they could dismantle my arguments, it certainly *would* be worth their time, since I think that their company is wildly overvalued and have often said so publicly (e.g. on CNBC yesterday).

@theo You are lying sack of something. I didn’t block you because you disagreed with me, but because you couldn’t get off the first two levels of the diagram above.

Since you are so butt hurt about it, I will give on last chance to be an adult.

Theo - t3.ggTheo - t3.gg@theo

He really doesn't like when you weaponize his own behavior against him. You guys definitely should spam his replies, pointing out the contradictory nature of his assertions. That would be terrible.

an elaboration of the Paul Graham reference:

Gary MarcusGary Marcus@GaryMarcus

Literally one of the most important essays could read, if you want to have a *productive* disagreements about anything, on X or anywhere else, is @paulg’s “How to Disagree”. It describes a pyramid. Everyone should be aware of it. At the bottom are things like name-calling, insults and ad hominem arguments. Slightly higher, but not a whole lot better is “tone policing” At the top is “refutuation” and even better “refutation of the central point.” That’s what disagreements should be. Because life is short, I block people (e.g the Theo dude who is going around whining about being blocked) who can’t get past the lower levels. In contrast, people who disagree with me on matters of intellectual substance with real arguments (@emollick, @peterwildeford, @flowersslop, etc) are super welcome! If you get blocked me and wonder why, study the chart. If you hate me and never want to see me again, that’s fine too, but I still recommend you study the chart. (Credit: chart itself is by @bigthink, adapted from Graham’s essay)

To folks who claim I am always wrong, I have a few questions:

Was I wrong that these systems would continue to hallucinate and be untrustworthy? That Sam was a liar? That these companies would struggle to make a profit? That neurosymbolic approaches would become more prominent?

Nope, nope, nope, nope, and nope.

“I have no idea why you tagged Paul Graham” means “I was too lazy to try to learn something”. Paul Graham’s piece on argumentation is brilliant, something everyone should learn from it. In the meantime here’s the cliff notes, from @Bigthink:
