There's a disconnect in that statement. The imagined superintelligence that people like the LessWrong cult speculate and worry about is not the same thing as the AI that LeCun is working towards. The cultists simply speculate, against all evidence, that they somehow could end up being the same thing.
It would be much better if the AI risk conversation focused on the real risks, which are human abuse of AI, which will have effects like increasing inequality and in general amping up the dystopias we're already doing a great job of building without help from AI. The "conscious superintelligent AI" is a scifi LARPing game that some people are getting paid to play, which some credible people seem inclined to confuse with reality.
> That seems like an absurd comparison
It's on point. Anthropologist Clifford Geertz proposed this definition of religion: "Religion is a system of symbols which establish powerful, pervasive, and long-lasting moods and motivations in men by formulating conceptions of a general order of existence and clothing these conceptions with such an aura of factuality that the moods and motivations seem uniquely realistic."
It's that "aura of factuality" that makes superintelligent AI "seem uniquely realistic" to the believers of this nascent religion, a.k.a. cult. But when you step back and actually look at the foundational tenets in a vaguely rational light, they evaporate.
