United States District Court filing system for court cases is written in perl. Horrible language filled with one liners that only makes sense in the mind of the now retired and gone programmers. Sadly, I do not know why we cannot pursue other technologies. Perl is a trap... buyers will be stuck for 30 years. Like a mortgage, but without equity or returns.
You might want to go ahead and inform those investors who bought Amazon or Booking.com stock in the early 2000s that their orders of magnitudes of returns were really no such thing.
