Now you can donate to Singularity Institute using Bitcoin.
Currently Bitcoin mining appears to be profitable as only bubble economics can be. Already some Less Wrong users have purchased GPUs and started mining Bitcoin. Please consider sending some Bitcoins to SI at address 1HUrNJfVFwQkbuMXwiPxSQcpyr3ktn1wc9
2014 Edit: Please donate Bitcoin by using the Bitpay link on MIRI's donate page. Thanks!
Edit: Response was written to original (brief) version of the parent (quoted below).
Encryption software has, at times, been legally declared 'munitions', the export of which can be a serious crime. Since an AI actually could be deployed as a weapon - and even a 'Friendly' version will be perceived to be causing massive destruction by at least one interest group - throwing that sort of label around would be comparatively reasonable. Not that I would make that designation. But I'm not a paramilitary organisation with relevant official status.
As for things that are not Weapons of Mass Destruction, try biological and chemical weapons (of the kind that actually exist). If you want to cause mass destruction use a nuke. Don't have one of them? Use conventional explosives. If you want to do serious damage with a chemical weapon... pick a chemical that explodes. That phrase is broken.
