A few points. First, mustard gas is not a bioweapon. It's a chemical agent. There will never be a cure because it's like saying that you have a cure for fire.

A few points. First, mustard gas is not a bioweapon. It's a chemical agent. There will never be a cure because it's like saying that you have a cure for fire. Second, the point raised above is that things like food preservation technology implicitly confer military advantage. The same is true of many lifesaving medical technologies, especially things like celox that treat trauma. And then there's cryptography. I find it hard to believe that you (or anyone on HN) support Joe Biden's approach to restrictions there. But that's quite clearly a dual use technology. Finally, I never said it was equivalent to a cure for cancer. I don't believe that, and it's disingenuous to put words in my mouth. But things like self driving cars probably will actually save lives, and even independent of that I think it's worth examining very critically what restrictions we as a free society are willing to impose to gain military advantage.
