LeCun says current AI models are a dead end for progress.

Sure. That's easily proven, as the Pacific Rim tech companies are all running laps around the American models in terms of efficiency and output.

It looks like two guys arguing about which dead end to pursue

They're both Snipe Hunting for the mythological AGI, because they're each invested in the idea of a Singularity solving all their problems.

LLMs have a set of niche useful applications, but these dudes are chucking that advancement aside in pursuit of Digital God.

With Roko's Basilisk bumping around in their heads, I can't help but detect a certain religious fervor, either. We really might have folks who believe they'll be tortured for eternity if they don't build AI Hellraiser first.
