I certainly don’t want to dismiss any individuals as tech bros. Tech broism is more like a natural phenomenon, which occurs when you lock exclusively privileged people into a room for long enough and then let them discuss user needs.
At some point, they’ll ask themselves questions like “Why do we need privacy?” and everyone else in the room will agree that they’ve never needed it either and then they’ll found Google.

I am very much at risk of this, too. I have to constantly go out of my way to try to re-adjust my perspective, so that I don’t completely miss the ball on what users actually need.

And places like Hacker News naturally form, because of course, we all do want to only talk about topics that we consider relevant. And folks whose needs are not generally considered relevant by the Hacker News community will look for different places, too.

I guess, a question you can ask yourself:
If you’ve ever interviewed a senior engineer who was for example black, gay, trans and/or a woman, did they frequent Hacker News?
