Oh, one thread degenerated into a ridiculous cryogenics debate. That's sad, I wish people on both sides of that debate had chosen to show Hal the same respect that other software pioneers were given when they passed away and were featured on HN.
Especially considering how much he and other early cypherpunks pioneered privacy-enhancing software that so many of us have benefited from (PGP and Bitcoin, to name two).
