Indeed, I certainly remember the days when Montreal was said to be the next "AI superpower".
How much of that was driven by the media predicting after Trump's election in 2016 that hordes of tech companies and employees would flee north of the border?

(Though I think MILA is kind of losing some of its lustre, both in terms of research output and quality. I guess it might just be that my friends there are mostly doing RL or cognitive research, which I both find to be pretty... unpractical? They give me a 1980s AI dead-end vibes, but that's obviously purely personal biais)
