I think you really missed the point of what these technologies and innovations actually did for society and how it applies to today, underneath the snark.
In the 1970's, if you got gifted a camera, and were willing to put in the work to figure out how to use it, you learned a skill that immediately put you in rare company.
With enough practice of that skill you could be a professional photographer, which would be a good , reliable, well paid job. Now, the barrier of entry is nothing, so it's extremely competitive to be a professional photographer, and even the ones that succeed just scrape by. And you have to stand out on other things than the technical ability to operate a camera.
That's...what's about to happen (if it hasn't already) with software developers.
