Agreed, but there is a lot of misinformation about the topic. I met developers that thought the GIL prevents you from running your program in multiple instances at the same time on one machine - which is obviously not the case. Sure, it's a problem for specific workloads, and Python will get there eventually - I just don't think it is a deal breaker.
