Electronics360: "8 Biggest Disasters in Tech History"

The title is

"8 Biggest Failures in Tech History"

but did tech history only begin in the 21 st Century and only include electronics and electronic devices? The only exception is practically the Betamax (maybe a couple others were in the late 20 th Century) in this history. What about the Titanic and the Edsel, to name just a few older examples somehow overlooked but fairly well-known?

There are even more you could add to the list of fails for the 20th century.

The numerous Electric car fails before Tesla. The Next computer system by Steven Jobs. It was supose to be the replacement for Mac but it never got a big following. 3D tv was suppose to replace HDtv now it all about the 4kUHD. And more.

The products listed as "8 biggest disasters in Tech History" seems new comers idea. I consider Tech History really came with industrial and consumer products and systems invented or developed those beneficiary to life and society, not for fun and joy. History starts right from invention of Tech products-....,....,....,............., Edison to new technology up to now.
