I didn't say there was anything wrong with amusement. I just asked if there was any utility besides that. If it's only value is amusement and the potential negatives are enormous, it's at least worth a discussion. I don't think it's right to just shrug and say "everything can be used for good or bad". The details matter. If you're talking about a Yo-yo, yeah, you can hit people with it or just amuse yourself; nothing catastrophic is likely to happen. This tech though has greater implications.
