Games are not going anywhere from a mostly C++ code base. New languages get adopted if they are too good to be true or they have enterprise adoption like Go. Even Python took 20 years to reach where it is now. Julia will take a long time to become a general programming language for all purposes.

Scientific Computing is a realistic goal just like Golang is a realistic language with Enterprise adoption. It may not be the most elegant language like Lisp but it is practical. (People don't want the perfect solution but one that works most of the time) (P.S I am vaguely quoting this from some anecdote about a discussion on Lisp and C)
