It would be good if one's reputation tracked one's track record of predictive accuracy. But many people will take what LeCun says as gospel regardless of how badly wrong he has been and continues to be.
I often see people vindicate those who predicted really fast takeoff to AGI / ASI, because the capabilities have obviously been taking off extremely quickly. But still not as quickly as many predicted! To me, the people who confidently predicted that we'd all be out of a job by 2024 or 2025 have been just as wrong as LeCun has been.
It's only online that I've seen these wild predictions, where it coincidentally is profitable to say them. These people are looking g for clicks or to stay relevant, so they have to say crazy stuff.
Being wrong, even badly wrong, is fine, so long as one adjusts their beliefs accordingly. LeCun has not.
