Extinction Event

It's kind of sad to watch Scheme, Python, and Perl self-destruct (and a pleasure to watch C++ go), but that doesn't mean we can't look forward to the future. What will take their place? Whose pet language will achieve widespread prominence? Perhaps Lisp will shake off the AI winter, or programmers will realize the value Haskell's Abstract Bullshite has. Or could it be something new?

Would you guys really want to find books like "Learn Lisp Macros in 3 weeks!" or "Monads for dummies!"?
Maybe I'm a bad person, but I kind of like to know that some languages are beyond the capabilities of a web developer who uses PHP.
