Me too. It was my favorite talk of the ones I saw.

I did like it to, but haven't seen any of the others, and usually don't like sitting through talks rather than reading transcripts.

But you got me curious, what other talks from the day/event would be worth watching in your mind?

I also liked Chelsea Finn's robot talk.

(I didn't see all the talks, so please don't take absence of recommendation as recommendation of absence!)
