The most productive and useful programming language you know, by a long shot, is English or Hindi or Portuguese or Spanish or French or whatever human language your team uses. Good communication skills are way more valuable to you and your customers than picking up a new language every year. That is, while there is value in the item on
the right, I value the item on the left more. Sound familiar?
Developers that name things well and program with a respect for human
languages create more maintainable and easier to follow code. Being able to communicate with a customer, analyst and/or product owner can save you hour upon hour of effort and keep your solution simple. No programming language no matter how syntactically minimal or internal DSL friendly can ever come close to this.
