I just, Katrin, why don't you jump in first and then Alon, love to hear your thoughts.

Sure.

A couple of things come to mind when I think about things I've changed my mind on or maybe my vision of.

One, I think when ChatGPT came out, we or I at least saw it as a way to have a conversation.

And I think that AI tutor presented itself as a use case that I think is not the most compelling use case right now for AI.

And I think that some of the recent research on AI tutors versus AI serving up something that an adult might intermediate to help a young person is actually much more promising.

And so when I think about a vision I had of even the nuance of the role of the adult, the role of the tech, it's not kids learn from technology and then humans do human things.

What does that really mean when we're thinking about this new instructional core, if you will?
