I agree, I think the problem was not a particular microprocessor, but a greater cultural issue. At the end of home computer era, a PC has became someone's workbench, end users are not expected to learn and write programs anymore. There were bright sides, Xerox Alto, GUI, desktop publishing, multimedia, widely-available programs, no need to repeat those stories, we all know them. Meanwhile, accessibility to programming has largely been lost in this process.
On second thought, it's not all black-and-white, some accessibility to programming still exists. On Unix-like systems, "python", "perl" is one command away, and even on Windows, JavaScript is one browser window away. If the next generation rewrites the computing history today, I wonder what tools/environment would be seen as the 21st century equivalent of 6502 and home computers. I'm sure it would have a dedicated chapter to Raspberry Pi and Arduino devboards at least.
