Somebody that has claimed 20 years of experience and doesn't at least know instantly (this doesn't require "thinking" about for minutes) that this is a one liner in the shell or a few lines of pick your poison script, Perl, Python, Ruby, who cares, even if they can't remember the specifics is not an expert in programming.

And I get it, there are highly specialized people that get very deep in the weeds in maybe HPC or embedded, even so most of them will at least still be aware, but moreover these people lack the knowledge to comment on programming or software engineering in the large, I wouldn't call them experts outside their limited domain if they really can't begin to know where to look to do a fucking permutation of a word list.

The old saying that for some 20 years of experience is 1 year and 19 repeats probably applies.
