&gt; Do you know FORTRAN?<p>a little<p>&gt; Do you know any programmers who know FORTRAN?<p>many<p>&gt; Do you know anyone who wants to learn FORTRAN?<p>many<p>&gt; Unless you&#x27;re in the community the answer to all of those is no.<p>Fortran is still widely used in mathematics and science. So if that&#x27;s the community bubble you&#x27;re referring to, then yes, there&#x27;s definitely a niche there in my experience (but not purely for legacy reasons).
