The initial reaction to doing another programming language is people say: 'We have one that’s sufficient'. Change can be hard for some people.
“In my quest it quickly became clear that web technologies have gained a lot of steam over the years, not just for web applications, but for desktop and mobile as well. I've found that there are hundreds of tools out there, and so far, but there doesn't seem to be the veritable Swiss Army Knife out there.” ~Nicholas Bilyk
