Back in 2010, most devs were using Java or C++. As any C++ dev will tell you, setting up 3rd party dependencies takes forever especially on Windows. In comes Python with its simple yet powerful core language features, batteries included philosophy, and tons of easy to install packages. That attracted a lot of attention from C++ and Java devs looking to get things done easier. It also attracted attention from systems developers looking for a saner alternative to writing Bash scripts. Not only that, but because of the simplicity of development, it became a core teaching language for learning programming. And because of all of that, it became even more popular when more math-oriented people needed a language to use for AI/ML. Ruby fits a lot of the same niches. I also remember experimenting with Ruby at the same time I was experimenting with Python. There's nothing necessarily wrong with Ruby. But it's an either/or situation, like HD-DVD and Blu-Ray. Ruby fell into obscurity almost because of the rise of Python. Because we now have a solid ultra-high level language with batteries included, there's less of a need to also focus on Ruby.
