To answer this question I would say no, no one will reach that level of fame in techno now as the likes of Mills, UR were pioneers of something new. However if the scene got of its arse and tried to pull in a younger crowd then maybe the whole thing could do a full circle with a slightly more evolved slant.

I think the real inventors of today are the people who create interactive devices/software and use them to advance their own personal expression. Those are the people who are doing something relatively new and can push back the limitations of a standard sequencing package.
