For hundreds of years humans have read printed books to learn things, without talking to teachers. Seems like a weak argument.

It isn't.

Software has enabled learning unlike any other even before in human history, the only previous time being when Gutenberg invented the printing press.

These days there isn't a thing on earth that I can't learn sitting at home. There is a huge difference.

Today only barrier to learning is your own motivation. Access to quality information has become so easy and cheap, that its hard time to blame somebody else for your failure.
