You have taken a FUD sound bite and repeated it without understanding. The language is not at issue here. CPython's GIL does not make threads useless at all, and there are already Python interpreters without a GIL anyway.
An addiction to globally shared state across threads multiplies race conditions and scaling problems, even if the GIL magically goes away. If you are incapable of using even processes effectively then I really fear for you when you have to scale out horizontally.
I'd say this more nicely if I could think of any way, but you don't know what you're talking about and you should read up before you begin talking about it again. It looks bad and you might mislead someone.
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.
