It's always cool when we can achieve a speed up in something, but I fear that we may have reached the point of Ruby becoming mostly irrelevant to the larger market. Python, thanks mainly to it's data science libraries, has taken it's place as the go to non-JavaScript scripting language. Unless Ruby comes up with some killer feature like it had with Ruby-on-Rails back in the day, I doubt that the speed up of Ruby will be what revives it for most people.
All of that said, I would love for Ruby to usurp Python from it's thrown!
Python did a good job offsetting speed issues by rewriting key parts of libraries in C (or maybe C++/fortran in some spots). I don't know if the same effort ever went into key Ruby libraries.
