I hate to be a negative Nancy, but if STM was going to take off it would have by now. Is there something I am missing?

Would it really have taken off by now? I really don't know much about STM, and I know there is no one canonical STM, but it's often compared to garbage collection. How long did it take for garbage collection to take off? Wikipedia claims GC was invented in 1959 and STM in 1995.

I think we need it but its just like with GC. You cant just not worry about it any more. Developers need to learn about STMs. How the work, what there problems are and they need to learn programming with these implementations STMs.

It depends on what you mean by "take off", and what type of STM you're talking about. I use Clojure's STM regularly, and to great benefit.

Yeah, I agree with wtetzner, I've been using STM in Scala via both ScalaSTM and Akka for almost 2 years now. It's incredibly easy to use and I use it far more than any of the other concurrency controls out there. I've written a blog entry about how to use STM in Scala and some pitfalls to avoid: http://outputstream.io/dear-scalasphere-why-arent-we-talking...

This is way to much simplification. The problem with STM is that it is very hard to integrate in classical languages. In Clojure and Haskell STM works really well and STM is just in production.

Given that Clojure is impure and has IO effects hidden behind seemingly innocuous evalation, how does STM work well in Clojure?
