  Intended tone was humorous, as in the ‘you guys have [X]s?’ meme, not to deny that Russia has such executives, although I haven’t seen anything notable from Sberbank. I’ve certainly kept an eye on Mistral and SSI if no one else.

  However right now I think I’d list at least 5 American labs and 4 Chinese labs as substantially ahead of anyone anywhere else until proven otherwise, excluding SSI which is impossible to get a read on.
