800 people might not fix the whole tech ecosystem (it is impossibly broken which so I can see why the author would like to just go work on something else). But if you got 800 people in a room to say thanks, I bet it would feel pretty cool.

(This isn’t intended as a full counter argument against your broader point, which I’m still not really sure either way about, I just wanted to note that sometimes we have small effects and that’s OK. We’re only individuals after all, it wouldn’t make sense to expect every person to change the world in some sense, it would be chaos).
