I am no one. I have greatest respect for all Turing award winners.
But one thing I am wary is that LeCun - while special and excellent - is just as many others, working at a place where "AI" is already used to "engage people up" - it is just the nature of the business if you are in the engagement business. And your "AI" will gladly help you in all kind of subtle ways. What is also nice is that it's uncharted territory now, so you can freely roam - and engage the heck out of your audience.
And LeCun is just - as a "neutral" scientist - just doing his part.
Why can't he not work at FB? Money? Data?
