And WT is not redefining a word. What they’ve done is date “this generation” from 1914 to at least 1992, in theory.
Car manufacturers do that all the time. They’ll place a fourth generation car, for example, between 1990-1995 and any car built in that time period is a fourth gen car.
It can lasts an long as their is at least 1 fourth gen car being driven. Once the last one is off the road, it can be said to be gone.
The denial of simple facts and logic here is astounding!
