Can Ruby Survive Another 25 Years? (techradar.com)
TechRadar marked the 25th anniversary of the Ruby programming language by writing "there are still questions over whether it can survive another 25 years."
The popularity of the Ruby language has been bolstered for many years by the success of the Ruby on Rails (RoR) web application framework which dominated the web scene, particularly among startups who wanted something that deal with much of the heavy lifting... But RoR, although popular, isn't the superstar that it was and It has faced fierce competition as issues such as scaling have become a greater concern for web companies. The JavaScript framework Node.js, for instance, has become popular as it requires less memory to deal with numerous connections because of its callback functions...
To improve performance further Ruby is introducing JIT (Just-In-Time) technology, which is already used by JVM and other languages. "We've created a prototype of this JIT compiler so that this year, probably on Christmas Day, Ruby 2.6 will be released," Matz confirmed. You can try the initial implementation of the MJIT compiler in the 2.6 preview1... Probably the clearest overview explanation of how MJIT works is supplied by Shannon Skipper: "With MJIT, certain Ruby YARV instructions are converted to C code and put into a .c file, which is compiled by GCC or Clang into a .so dynamic library file. The RubyVM can then use that cached, precompiled native code from the dynamic library the next time the RubyVM sees that same YARV instruction.
Ruby creator Yukihiro Matsumoto says Ruby 3.0 "has a goal of being three times faster than Ruby 2.0," and TechRadar reports that it's obvious that Matsumoto "will do anything he can to enable Ruby to survive and thrive..."
And in addition, "he's thoroughly enjoying himself doing what he does... and his outlook is quite simple: Programming is fun, he's had fun for the last 25 years making Ruby, and at the age of 52 now, he hopes that he'll get to spend the next 25 years having as much fun working on the language he dreamt up and wrote down in -- a now lost -- notebook, at the age of 17."
"We want Ruby to be the language that is around for a long time and people still use," Matsumoto tells another interviewer, "not the one people used to use."

People are looking at this from the wrong perspective. No offense meant, but I think that includes you too.
I rather suspect that you are a long-time Windows-based programmer.
Of course C is more performant. It's not a high-level language. It is intermediate-level at best. That's why C++, for one example, is higherl-level and therefore easier to use but slower. And interpreted languages will always be to some degree slower, because of their very nature. But they are also capable of doing more with less programming effort, and that is THEIR forte.
Further, there are fully-compilable versions of Ruby, such as MacRuby and jRuby. They don't give up very much to become compiled; only a few convenience features.
As for C libraries, that's partly what scripting languages are FOR: tying together low-level efficient libraries into higher-level finished products.
You say "for the real work, people will always turn to native code" but that's plain BS. People and companies do not have time or budget to low-level-code everything they do. A smart programmer will use the language appropriate to the task, and that often means tying that "native code" together using higher-level languages.
Your opinion of Python, for example, is just wrong. Python, despite its language inconsistencies and weird significant-white-space formatting, has been adopted by the scientific community as probably the go-to language of choice. It may not be used commercially as much as some others, but it is going to be around a long time.
The long and short of it is: each language has its particular strengths and weaknesses. Industry watchdogs predicted the imminent demise of Ruby over 10 years ago. That hasn't happened. In fact only 2 years ago, experienced Ruby programmers in the US commanded the highest salary of any language. I haven't checked more recently. But the market is a good place to look when one is making such "predictions".
While Ruby is 25 years old, it did not gain wide attention in the United States until nearly 10 years later. So as a practical matter, in the US, it is 15 years old.
It is approximately as performant as Python, and has a more consistent structure and syntax, so I suspect the scientific community will eventually shift over to Ruby over Python, unless it skips that step altogether and goes into functional programming.
As for Ruby "scalability issues", that is a myth that has weirdly persisted for at least a decade, in the face of abundant contrary evidence. Here are companies that have had no trouble at all scaling Ruby: AirBnB, Fiverr, Github, Goodreads, Groupon, Hulu, Indiegogo, Kickstarter, MyFitnessPal, Pixlr, Scribd, Shopify, Square, Strava, Twitch, UrbanDictionary, WhitePages, and ZenDesk.
There are many more, of course, but those are just some names that people might recognize.
