No, you have taken a "stick my head in the sand and pretend the last 30 years of progress didn't happen" and repeating it without understanding. I do web development in haskell. I have thousands of concurrent connections to a single process, which is using 32 cores without problems. There has not been a single race condition, deadlock, mutex bottleneck, etc, etc. Just because you are happy with an absurdly primitive language, doesn't mean those of us in the 21st century are ignorant.
