That will backfire on employers. With the shortage of seniors with good skills, the demand will rise for them. An employer that squeezes his seniors will find them quitting because there will be another desperate employer that will treat them better.

Ruby was the most approachable language I found and sheparded me from my limits of bash scripting and Windows batch file scripting into the next level. The author derides Ruby's easy readability and syntax because it has issues scaling to large enterprise applications. I don't disagree there is a performance ceiling, but how many hundreds of thousands of Ruby projects never rose to that level of need? The author is also forgetting that Ruby had Rubygems for easy modular functional additions years before Python eventually got pip. I don't write in Ruby anymore, and Python has evolved to be much more approachable than it was when Ruby was in its prime, however if someone came to me today saying they wanted the easier programming language to learn that could build full applications on Linux, OSX, Windows, and the web, I'd still point them to Ruby with the caveat that it would have limits and they would be better served by Python in the long run.
