Paul Graham wrote an essay : "Why There Aren't More Googles" --- http://www.paulgraham.com/googles.html.
In it, he referenced an essay by Umar Haque who wrote on the same issue. The link is in the first line of the essay.
I clicked it, but it gave an error message : https://hbr.org/error/page-not-found
Anyone knows where I can find a working link to this essay ?
