> Perl is extinct in comparison.
Which is a good example that the decrease in use can go a lot faster than you think. Perl was widely used in 2000, and thought to be on par with Python. Similarly Visual Basic which nobody seems to remember any more.
Also, COBOL is simply used because it is uneconomical to rewrite those old programs, not because it is a good language to write new stuff in. But the heavy dependency of Python programs on libraries hosted across the web means that obsolescence can happen a lot faster today; a COBOL program is almost totally self-contained in comparison.
