Because that would imply that your favourite language is a failure, and you find that conclusion unacceptable?
Hardly.
My personal tastes don't enter into it. I've slung enough (read hundreds of KLOCs) C or C++ to recognize the fact that its commercial success is more of an historical accident than a testament to its characteristics. Also, I'm something of a dilettante when it comes to Lisp; however, that hasn't kept me from appreciating its merits.
Lisp is a power tool for a Very Smart Person. Like all such tools, they're difficult to master. The truly successful stuff tends to be usable in an effective manner by people who aren't VSPs.
I think we're in agreement here. However, again, this doesn't speak to the technological "disposition" of the language. In fact, this seems contrary to your point about the marketplace favoring the best technology.
