Languages don't get popular unless they are very easy to learn, so no language popular today almost surely is biased in favor of learning curve and against complexity. We probably need some big industrywide intervention to create the optimal level of complexity in languages as I doubt even C++ is too complex to be optimal if you consider that you work 40 years in a career. It would work by just having a couple of standard languages so developers don't need to learn so many languages, then they spend a lot of time learning those until they are fluent and then they don't have to learn anything new about programming languages for the rest of their lives, very efficient.
