I agree with the message overall: impactful work might not 'look' like work, but I'm not sure what the author's deal is with conflating 'collaboration' with 'meaningless meetings'.
I guess I've just had different experiences, but for me, 'collaboration' means 'understanding that this project/task does not exist in isolation and looping in those relevant stakeholders early to make sure they decide with you as opposed to discovering roadblocks too late'. I can't imagine how someone can be against that.
From context, I feel like the author is using that word to mean 'gather people in a room and pretend to work'... is that how it's used normally?
