So fuzzy logic tries to mimic the way humans reason. So, because classical logic is very precise, there are many people who don't like fuzzy logic. And so when you talk about fuzzy logic, to them this is undesirable. They don't like it. So fuzzy logic has been and still is to some degree controversial.
Some people say it's a good thing, some people say that it's a bad thing.
Fuzzy logic today has many different uses. It's not concentrated in just one thing, it's very broad. You know, World Scientific has become quite visible now. And so I get quite a few pamphlets, advertisements, literature in the mail. I have an envelope marked World Scientific.
