It's not that simple, I doubt the boomers working at Google now are the one creating problems and preventing the company from moving forward.
When you see how much stuff they did for ahead of their time ( Big Table , Piper etc...) and now the same tech is being ported to the cloud.
My point here is to say that it's a mentality issue rather than an age issue. If the companies you are working did not invest to transform you and to make you adequate toward current society , you are going to slow down your company otherwise you'll be just fine.
>I’m also tired of all of this inexact labeling of “generations”
The age group are identified page 3.
I personally consider this labelling accurate , but as you mentioned it "boomers" are okay to label others but not to be labelled themselves.
