The blog doesn’t have an about me page as far as I can tell. Google says Dan is a systems engineer at Nvidia.
Edit: Found the About page https://danluu.com/about It's at the bottom of articles, but not accessible on the home page.
If this were an actual technical topic, I'd be more inclined to continue reading, but here, it's musings framed as a life lesson that could have come from anyone in my circle of friends. Life lessons from people whose only achievement is working at big tech. At least for my friends, they don't walk around assuming they're smarter than people.
The reoccurring theme in this post from Dan is he's not the one that's stupid, it's the people around him who are too stupid to see his underlying genius. Dan comes off insufferable.
