Being a popular AI influencer is not necessarily correlated with being a good researcher though. And I would argue there is a strong indication that it is negatively correlated with being a good business leader / founder.
Here's to hoping he chills out and goes back to the sorely needed lost art of explaining complicated things in elegant ways, and doesn't stray too far back into wasting time with all the top sheisters of the valley.
Edit: the more I think about it, the more I realize that it probably screws with a person to have their tweets get b-lined to the front page of hackernews. It makes you a target for offers and opportunities because of your name/influence, but not necessarily because of your underlying "best fit"
Here's a gem of educator. Check out his other videos.
MOCs are great for access, but they are not, and definitely should not be treated as, replacements. That I am certain will have a net negative result. I'm in grad school and there's something I tell students on the first day:
> The main value in you paying (tuition) and attending is not just to hear me lecture, but to be able to stop, interrupt, and ask questions or visit me in office hours. If you are just interested in lectures I've linked several on our website from high quality as well as several books, blogs, and other resources. Everyone should all use these. But you can't talk to a video or book, but you can to me. You should use all of these resources to maximize your learning. I will not be taking attendance.
I'm sure many of you have had lectures with a hundred students if you went to a large school (I luckily did not). You're probably aware how different that is from a smaller course. It's great for access and certainly is monetarily efficient, but its certainly not the most efficient for educating an individual. MOCs are great because they increase the ability of educators to share notes. We pull from one another all the time (with credit of course), because if someone else teaches in a better way than I do, I should update the way I teach. MOCs are more an extension of books. Youtube is the same, but at the end of the day you can't learn math without doing math. Even Grant states this explicitly.
