If the cpunk list discusses only crypto, then mathematician-programmers will do their cold work in an isolation which eliminates the need to think about the consequences of their actions. So discussions on philosophy, society, etc., are important, to remind everyone of the context within which this subject operates. However, if "community feeling" is the only thing created on the list, and crypto is no longer the focal topic, then what is to be accomplished: the list will become just a playing ground for wayward KOTM PhDs who are not welcome in most other cyberspaces. So the question of "how will this impact society", must maintain association with "but how does this relate to crypto?". (unless the list has changed its stripes, evolving into something completely different, which many will agree it has). .. Blanc
