I agree with you mostly, but let's also consider the value of lowering the bar of entry. Once upon a time "software engineer" meant someone punching cards and running them through one out of a handful machines on Earth to execute a piece of logic. In 10 years from now "software engineer" might mean someone who practically draws something on a touchable, wireless surface that weighs less than a couple of those punch cards that used to hold a single logical instruction, and their software is instantly available to billions of people.

Or to translate to your analogy: there might have been a lot of brilliant writers in the world that simply never learned how to write, or they never had access to distribution so the only person who read their masterpiece was themselves. Today, with the Internet and computers and better access to schools, we have a lot more writers. There might also be more lower quality content because the bar of entry has been lowered, but I'm absolutely sure there will be a lot more high quality content as well.
