I read the comment as "allowing wealth to access the skill of the people who created the contents of the training set." I don't think anything prior has allowed such direct access to the skill of other people while denying them access to wealth. At least the creators of stock photos and templates get paid.

How so? Computers haven't been prohibitively expensive since what, the 80s? Anyone with access to one could teach themselves to program and make money through free resources (well, you needed to pay an ISP, of course). I did just this back in early web days and wealthy people would to give me their money in exchange for my skills with technology. What am I missing here?

Not really, no.
