It is worth noting that the bellyaching about business going away is not without merit.
Our society as a whole is moving in a bad direction. Technology and globalization allowed photography, and 100 other trades, to be eliminated as viable jobs. There's no law that says these need to be replaced with other equivalently viable jobs.
Henry Ford deliberately paid his guys enough so they could afford his cars. Henry could do math. Modern corporate leaders cannot. The goal is to produce products that can be afforded by people who work for someone else.
The march of technology is an inexorable component here, but so is the modern corporate attitude of placing profits first (and this is a very modern idea, make no mistake). Photography wasn't ruined by Apple paying people pennies a day in Bangladesh to build iPads, but there are similarities and relationships.
Guilds and unions put people first. Well, that's the idea, anyways.
The loss of each individual career, be it photographer, buggy whip maker, tailor, cobbler, or what have you, makes sense as a consequence of natural economic forces. Overall the pattern is driven as much by corporatism as economics, though.
When they come for your career, rest assured, there will probably be a few people left to explain how it was inevitable, you have to adapt, and perhaps you were just very bad at it. When we reach endgame, with 500 CEOs building products with near slave labor, products that there's nobody left on earth that is paid enough to buy, well, I guess we'll see some changes.
