Yes, which goes to the point of the book: the major innovation and mainstreaming of technology occurred "until the late 60s or 70s". You're making the same point as the book is.
Also: photocopiers, https://en.wikipedia.org/wiki/Xerography
Edit: the authors of the book do say that the mainstreaming of computers and the Internet is one of the post-1970s innovations.
The only reason I mentioned fax is because that’s a thing that only became widespread after all innovation had supposedly stopped. BUT it already has been obsolete for decades and replaced by more advanced technologies.
> the authors of the book do say
That’s like saying that there wasn’t much innovation in the late 1800s besides electricity.. Yes if you exclude the area there has been the most progress in your point might have some very superficial merit
Computers and internet transformed plenty of those devices that were apparently already perfected by the 70s.
Except devices like TVs have almost nothing in common with their equivalent from back then besides the name and the fact that they show pictures. So television and CRTs weren’t real inventions either? They are basically the same thing as film projectors and those were a thing back in the 1890s. Really if we think about it almost nothing worth mentioning was invented after 1899..
Offices didn't have them until the late 60s or 70s which is what matters.
It's like saying that people could make video calls back in the 30s...
> the four biggest factors
Yet there were almost 2x more fatalities per same distance driven back in 1980 and almost 4x in 1970
