You are probably right.
I've come across JWs who are years behind in any changes, in anything.
Never mind anything to do with the "generation" teaching.
They try to juggle the "generation" because they thought "the end" would have been here long ago.
How we used to watch the numbers of the "anointed" falling and think "the end" is not far away now.
Now they are thrown into turmoil because numbers are rising.
The rank and file just tuck away any change and just think to themselves "the end will be here soon".
No matter how many years they have been saying it.
The "generation" change makes it so that the "the end" can be any future time.
Yet you get them going round "there's only three years left of this system"
Or you can bet after this years conventions they will be saying , as they have done every year.
"It will be here by the end of the year."
Then another year will pass and so on.
For the WT its one of the ways they hang on to members.
The carrot dangling in front of them.
