Hi, I'm a newbie to fuzz logic & fuzzy sets. Searching in the web, the
pages that talk about fuzzy are last actualized about 2005/2006 and
before. Nothing new, forum, blog or something (I don't find them). Only
"fossils".

What's happening? The fuzzy was a bubble? The golden age of fuzzy it's
over? Why?

You're seeing the results of not knowing what you're looking for. There's
tremendous output of fuzzy logic controllers, but they're so mainstream now
that it's not worth mentioning.

There are also many approximate reasoning models in a variety of business
and scientific fields. These continue to be proprietary implementations of
fuzzy inference engines so you're not going to see them advertised as
available in shrink-wrapped packages. Many business applications provide a
competitive advantage to the companies for whom they're developed, so
there's no major news stories there. Not long ago, The Economist published
their Technology Quarterly. This included a fascinating (to me, at least)
story of a company that writes software to advise retailers when to mark
down merchandise, and by how much to mark it down. Nothing in the article
mentioned fuzzy sets or fuzzy logic, but it's obvious to those of us who
work with these models that this is the only way to create a functioning
model. This product, by the way, sells in the 7-digit range per customer.

As far as academia is concerned, I've no idea. Historically, the research
and other writings from this venue have little relationship to the
non-control applications in the real world of business and commerce.
