> most people have better things to do with their time than rewrite something that already works
These people just went from "never programmed before" to "knowing how to program" - I doubt people that made an investment like this would "stop to the first tool" because "it works". Sure, they might not rewrite something that works, but they would wonder "is there a better tool to do the job?"
You can of course target "what is the minimum I can do on this and then be able to focus on my job" and never worry about other issues (could I have done more? could I have done better? is it extendable? is it maintainable? etc.) but that is more about how you view "your job". If you are a doctor and your job is "heal patients" then learning another programming language is not your job. If you are someone maintaining some tool written in a specific language, then learning another programming language is not your job. If you are a software engineer that can solve multiple problems, wondering if you should know another programming language is part of your job.
