There was a young women who grew up in my hometown in Ontario who was very brilliant.  She went off to UoT and eventually earned a PhD in Mathematics.  I knew her family and I was told that upon graduation that the very few offers that she received from Canadian firms were basically insults.  There was nothing offered from academia.  She reluctantly went to the US.

Where is she now?  She heads-up the Artificial Intelligence research program at the Stanford Research Institute in California.  That is basically THE TOP AI research institution in the world.

I was reminded of her recently when I happened to hear her interviewed by NPR when they were doing a story of how Amazon is planning to use automation in their facilities.

That's the story of Canada.
