> "Best people" according to what metric, other than salary?
Facebook scales. It’s not easy to scale computing infrastructure to support billions of daily active users. Only a handful of companies can do that right now. On top of that they scaled an ad business that can target billions of people. There is only one other company in the world who can do that.
> What technology has Facebook developed with all of those "best people" that could compare to what Bell Labs did with a group of fewer than 10?
See it’s less about “quality”, it’s more about “quantity”. Scaling is a different problem on its own. I adore Unix but I admire what Facebook did as well. Scaling any project over 10 exceptional people is one thing and scaling a project with 10,000 engineers is a completely different thing and Facebook succeeded at that.
Whether that’s a good thing or not that they have succeeded is a separate discussion.
