I remember in ~2005 people said almost the exact same thing about Python and Perl.
Python 2.0 was released in 2000. Python 1.0 was 1994, and Python 0.9 (first public release?) was 1991.
Check the google trends. https://trends.google.com/trends/explore?date=all&geo=US&q=p... Its unclear when perl peaked since it has been in decline since before 2004 But it wasn't til late 2007 that Python overtook Perl in google searches
Even while it was in decline people were still making that argument.
