So you'd never hire someone like Paul Graham after he has worked for 10 years in Lisp projects, or some guy doing 10 years of embedded C work, etc...

Using "lots of" technologies is a meaningless metric, except if you want a code monkey to work with whatever for some startup where everyone has to wear 10 hats.

If I was building the Curiosity I would get a guy with 20+, not 10, years of experience in just embedded C (or Ada or whatever).

If I was planning a new JS heavy web app, I would get a 10+ years Javascript wizard. If he had the JS chops I could not care less if he also dabbled in Haskell or APL.

If I was trying to find the best Lisp developer out there I would hire Paul Graham, and if I was trying to find a senior person in C I would hire someone with 10 years of C.

So I think you are just clarifying my point here.

The OP has 10 years of experience in java. so I would consider him for a java developer position. I don't believe that is what the OP wants though.
