It's all about being productive
Stuff like this makes me sad:
Have all these years of shedding words over it solved anything? Frankly: no. We are still seeing a large combination of languages being used and all of those projects have good reasons to do so.
It really doesn’t matter
Most open-source projects (or modules) don’t have a ton of contributors. It’s usually a modest team of core maintainers/developers that do the bulk of the work. And that’s fine: the success of a project should not be measured by the number of contributors, but by the quality of the software it produces.
This smallish team of core developers will have their own good reasons for picking up a certain language. They’ll use the language that they feel most productive with for the task at hand. And that’s a good thing, they are mostly the people that move the project forward.
The biggest barrier to contributing on a project is not the language, there are plenty of projects written in unproductive languages that get a ton of contributions. Any good programmer can pick up a new language up quickly (and TJ is more than just a good programmer, he’s a fantastic one, much respect). The bigger hurdle is the specific domain knowledge involved.
Let’s all agree to disagree and have some respect for each other’s opinions, they are all valid anyway.
PS: I’ll be heavily moderating comments that try to turn this into a flame-war. I’m writing this to find some more respect and understanding.
