That is such hyperbole. I have no formal IT background and I taught myself the Linux command line, Python, and Emacs in the course of a single year after I heard about this new Linux thing that was free to install. This was 2000, and from communities like Slashdot I saw there were plenty of other nerdy young people taking up the CLI and other Linux stuff, just out of curiosity and without any connection with the IT industry.
Sure, none of this software will ever appeal to the broad masses*, but since the 1990s programming has become so much more accessible to the general public, because of both the free-of-charge software and the free-of-charge documentation. Learning to program on earlier platforms could be very expensive.
* Still, I have heard rumors of a corporation in the 1980s where the secretarial staff – middle-aged women with no formal computer-science education – wrote some custom Emacs Lisp and/or Awk. Maybe learning even relatively arcane stuff can be done by anyone if their salary depends on it.
