Above, you wrote <<velocity>>. Most people would say that C++ has lower velocity than other higher order languages, like C#, Java, Python, Ruby, etc. You also include the term <<experience>> which is a curious combination. In my professional experience, language "experience" dominates most discussions about what langauge to use for a new project. After all, programmers are humans who have biases from their (programming) langauge experience. (Zero trolling on the last sentence!)
