I wasn't expecting really to work on a next breakthrough algorithm, and such (although folks in my team actually worked on some incredible statistics related stuff - and this is where I understood I know nothing about statistics).

Plenty for everyone, I think. I'm glad I was part of the experience!

As an ex-game tools developer (back then, and back again - current job), it was quite a change for me. If I haven't learned enough, then at least seen things from quite different perspective.
