I don’t understand Yann LeCun‘s reaction considering reputation of the company he works for - they should have already copied and integrated it somewhere.
The issue isn’t that Yann didn’t publish an AI app; it is that they did, and it was not as good.
The reality is that OpenAI was lucky. Inside the company, there is an alignment department whose effort was driven to help models share human ethics, and that was initially a bit marginalized. However, one of their projects, RLHF, ended up producing a much superior language model, when they could have initially assumed it would be worse.
