This is a genuine question, not trying to yuck someone's yum. I don't understand this style of writing. I can't really relate to the humor. Can someone explain the laugh people get from this?
I totally understand not getting why it's valuable - I'm not 100% on board either. But you're asking why it's funny to talk like a caveman? You might as well ask why farts are funny.
Maybe this one's execution isn't great, and maybe the joke doesn't work at this length - but the origin of the humor? Not to be insulting, but that's akin to a Lieutenant Commander Data question...
It started with https://grugbrain.dev/ but I think its useful because it dispenses with any possibility of pretension and signals 'this is simple advice about the fundamentals'. The limited vocab means no jargon bullshit. I find some of it really insightful. It speaks to the truth that beneath all the layers we are just hominids who have accidentally given ourselves great powers, and day to day a lot of what we do can be explained in simple terms and there is value in admitting that.
