A few people tried to excuse the slow python, but as far as I know the story, excuses are not necessary. Truth is that python was not meant to be fast, its source code was not meant to be fast, and its design was not optimized with the idea of being fast. Python was meant as a scrypting language that was easy to learn and work with on all levels and the issue of its slowness became important when it outgrew its role and became an application language powering large parts of the internet and the bigger part of the very expensive ML industry. I know that speed is a virtue, but it becomes a fundamental virtue when you have to scale and python was not meant to scale. So, yes, it is easy for people to be righteous and furious over the issue, but being righteous in hindsight is much easier than useful.
