Workplaces are where many of us spend a large percentage of our waking lives. So, it is "normal," unfortunately. This is why HR language and norms have broken containment into the non-work world. (Whether that's a good thing is another question.)
There is not one single discourse norm to rule them all and calling out every little thing as too offensive is just annoying. Yeah, yeah there are no midwits, everyone is a unique little genius flower, yeah.
More productive? Sure, to an extent.
Being merely more productive is a tame claim for what some people unashamedly post here
Karpathy, Carmack, Terence Tao, Simon Willison etc. are all smart people and manage to use AI effectively and productively because it doesn't hurt their ego.
