Even if it did nothing more than piss off fElon, it would be worth it (I say as an American).

One thing to note, though, with the current situation in the US is that people are deciding against coming here for work in many of those sectors. From science and engineering to doctors and college professors, I’ve heard multiple people saying that their European colleagues have turned down jobs in the US.

Canada has been fighting a war on science almost as long as the US (I remember hearing about issues with the conservative government in Canada back during the 2000s), but this is a real time of opportunity to bring smart people in.
