"No, not even close. 1984 was the height of the home computer boom, and businesses, by that point, had a personal computer on most white collar worker's desks. Games consoles had been pretty much killed at that point (https://en.wikipedia.org/wiki/Video_game_crash_of_1983), mostly by Jack Tramiel's war on Texas Instruments (!), and would take another half decade to start to become popular again. The Mac had just come out and was considered an impulse-buy personal computer.
I always love how some know-it-all takes the narrow view on a comment. Maybe what your saying is true in industrial big town USA but not where i was from in small town outliers. The PC boom didnt happen spontaneously overnight and neither did the so called game console crash. If consoles did crash we wouldnt have had 3rd gen Ataris, 2nd gen INTV, Coleco, Lynx, Amiga among many others. I could made make a strong argument that PCs in everyday were not widely accepted in the household and only really became popular after businesses began switching over.
"Typewriters were already looking antiquated at that point. Businesses bought word processors. Authors bought cheap CP/M machines or IBM PCs or other 8088 based personal computers."
I wasnt talking about businesses at this point so whatever. Looking antiquated vs practical reliability are two different things. My folks' insurance agency switched to Wangs in the mid 80s and still did much of their paperwork on the typewriter as did those of us still in school.
"The Unix PC was just absurdly expensive. That's the explanation. Had it sold for under $1,000, the world might have looked very different. But under $1,000 is tough for an OS that requires a hard disk."
Maybe you dont know that even a full C64 build could cost 1k by the time you bought the computer, monitor, hard drive, floppy drive, discs, printer, cables, landline...all of which was pretty out of reach for most of us living in the 80s.
