On an unrelated note, this exodus from Russia is yet another test of the popular (some places) lore that Jewish contribution is essential for national success, at least in science in technology. Germany seems to have done OK without, and Poland is not in total ruins, either.
Jews is just a a group of humans with certain statistical properties. Science could "exist" without them, no test necessary - they are not a magic ingredient. They did constitute very significant part of Russia's science establishment (despite quotas) and Russia was arguably #2 science producer in math and physics, and this % of their scientists and teachers leaving might plausibly knock them down a few levels. But Russians are certainly plenty smart - Mendeleyev, Kolmogorov, Gamow, etc. etc.

The nice thing about Russians (I'm from that neighborhood originally) is that they are absolutely crazy and will try just about anything. They also probably have/had second-best science culture behind US (though they suffered significant brain drain as huge numbers of educated Jews left in the last 25 years). They have less regulation and quite a few rich people with ideas. Seems like a worthwhile group to keep in touch with.
