Isn't this just a case of over-fitting? Recent LeCun has perhaps been over-fitted to Marcus's past writing. Maybe some augmentation (with new ideas) will resolve the issue?
I mean, there's that old saying about "standing on the shoulders of giants" and similar refrains for a reason. All science is cumulative and builds on things that came before. And a lot of times it seems that old ideas "go dormant" for a time, and then come roaring back due to some small tweak or change in available technology, etc. See the entire history of neural networks for example.
So I guess I'd say that if Gary has a legitimate beef, it would just be in regards to acknowledgement / citation / whatever. If Yann really was familiar with Gary's older work, then came around to the same ideas, but refused to acknowledge Gary, that could be seen as somewhat petty and vindictive. That said, I have no idea to what extent that is actually the case. Not trying to take sides here. I respect both guys to a tremendous degree.
