What do these languages have in common.
The programmer.
Without the programmer with general intelligence they do nothing.
They cannot make a process mechanical without the help of a person

Further most languages have other things in common just as many of our human languages have many things in common.
These things share ways of storing information in memory and retrieving them for purpose.
Learn whats common have those things benefit you.
Find languages that fit your problem and use those tools to solve the problem, or if the language that you know well can solve the problem
do not be concerned if some might call that work out of date. Does it matter if the problem is solved.
That and by using whats common most often one can simply explain the solution for the problem and the problem can be solved then by someone else
or yourself in another language.
The real difficulty is finding a problem that an individual is interested in and then sticking with that problem.
Perseverance dedication discipline and creativity solve problems.

Who knows maybe you will solve or create problems people have or will dream of for years to come.
