Back then, I would religiously read every workplace posts from Carmack (that wasn’t hidden to other orgs). I loved everything he was saying, I always found it really insightful. It also seemed clear (much before he went part time) that he was saying that on the outskirt of the project.
There’s a big culture of flatness at fb (and now meta). No titles are public, and you’re supposed to respect everybody’s opinion in the room. You’re supposed to lead without authority: by convincing people. You’re also quite free to explore things, as long as you can make a case for it.
There’s upsides and downsides to such environment. You can really multiply yourself if you create trust and clout. On the other hand, authority and a big title doesn’t always gives you room for directing a project.
I was always wondering how effective Carmack was going to be in such an environment. He doesn’t seem to be the type to lead, but I can see this happening in a small team, but an entire org that’s growing extremely quickly? For the kind of things he wanted to happen you’d have to make sure to hire people who cared about exactly the same kind of stuff, which doesn’t really happen when you’re in a diverse environment. Extremists must then spend their time pulling the group in one direction or the other.
