What would Russia gain from nuking Ukraine?
He did not threaten to nuke Ukraine. He threated to use nukes against NATO countries if they get directly involved in that conflict. Not a direct quote, but a summary would be “We know we can’t win war against NATO, but we still have nuclear weapons—there will be no winners”.
Gwern makes good case for use of sidenotes, and offers a few existing technical solutions.
I like how he uses it on his website and wonder why LW does not want to follow his example.
Are there any known problems with the idea/existing implementations that I’m missing?
