That talk was a great overview of the issue.

Most people who are ignorant about the subject always assume the GIL is stupid and useless, but the GIL allows Python to be extremely fast in single threaded scenarios, and any attempt to remove it introduces at least 20% slow downs.

And C extension support is also a huge factor as you mention. All of Python's scientific modules would be lost if they broke that.

The author assumes these are simple problems that can be solved but aren't because of politics or incompetence, but some of the smartest mind have attempted and failed.

I'd like the author to try and come up to solutions or at least draft ideas for how each of his points can be fixed. A lot of those are easy to state but difficult to solve without breaking more stuff.
