Really excited for this. Once some more time goes by and the most important python libraries update to support no GIL, there is just a tremendous amount of performance that can be automatically unlocked with almost no incremental effort for so many organizations and projects. It's also a good opportunity for new and more actively maintained projects to take market share from older and more established libraries if the older libraries don't take making these changes seriously and finish them in a timely manner. It's going to be amazing to saturate all the cores on a big machine using simple threads instead of dealing with the massive overhead and complexity and bugs of using something like multiprocessing.
