I'm not saying it's hard to learn. But we have teams in three countries who have more than enough work to do already. When they have to support what my team is building, they don't have the luxury of taking a week to learn a new language. I can't really sell that plan to our CTO, adding the inconvenience of a niche language to a project's other significant risks. We program in C++, with a sprinkling of Python or whatever else is needed to keep stuff building. I wrote an iOS application for us in Swift, but I'm the only one there who knows it.
