I just noted in a reply that and useful technology will be misused, often before the beneficial uses become widespread. And in some cases instead of beneficial uses ever becoming widespread.
I was talking about molecule cloaking, useful to ignore contaminants in a sample analysis, but P-to-P file sharing comes to mind. It seems in France that any software created, even for a legitimate purpose, is your liability if it is misused. I fail to see how any car companies or wineries exist there, since their products are misused in a common and highly visible way.
