John Carmack, legendary game designer, rocket guy and VR enthusiast, has announced that he is leaving both Meta/Facebook and the virtual reality business itself, after a decade as one of its most prominent champions.

Carmack’s position was as an executive consultant. He initially sent his farewell message to colleagues in an internal memo, but when that was leaked in part to the media, he decided to post the whole thing—including some clarifications—on his Facebook page instead.


Here it is in full:

This is the end of my decade in VR.

I have mixed feelings.

Quest 2 is almost exactly what I wanted to see from the beginning – mobile hardware, inside out tracking, optional PC streaming, 4k (ish) screen, cost effective. Despite all the complaints I have about our software, millions of people are still getting value out of it. We have a good product. It is successful, and successful products make the world a better place. It all could have happened a bit faster and been going better if different decisions had been made, but we built something pretty close to The Right Thing.

The issue is our efficiency.

Some will ask why I care how the progress is happening, as long as it is happening?

If I am trying to sway others, I would say that an org that has only known inefficiency is ill prepared for the inevitable competition and/or belt tightening, but really, it is the more personal pain of seeing a 5% GPU utilization number in production. I am offended by it.

[edit: I was being overly poetic here, as several people have missed the intention. As a systems optimization person, I care deeply about efficiency. When you work hard at optimization for most of your life, seeing something that is grossly inefficient hurts your soul. I was likening observing our organization’s performance to seeing a tragically low number on a profiling tool.]

We have a ridiculous amount of people and resources, but we constantly self-sabotage and squander effort. There is no way to sugar coat this; I think our organization is operating at half the effectiveness that would make me happy. Some may scoff and contend we are doing just fine, but others will laugh and say “Half? Ha! I’m at quarter efficiency!”

It has been a struggle for me. I have a voice at the highest levels here, so it feels like I should be able to move things, but I’m evidently not persuasive enough. A good fraction of the things I complain about eventually turn my way after a year or two passes and evidence piles up, but I have never been able to kill stupid things before they cause damage, or set a direction and have a team actually stick to it. I think my influence at the margins has been positive, but it has never been a prime mover.

This was admittedly self-inflicted – I could have moved to Menlo Park after the Oculus acquisition and tried to wage battles with generations of leadership, but I was busy programming, and I assumed I would hate it, be bad at it, and probably lose anyway.

Enough complaining. I wearied of the fight and have my own startup to run, but the fight is still winnable! VR can bring value to most of the people in the world, and no company is better positioned to do it than Meta. Maybe it actually is possible to get there by just plowing ahead with current practices, but there is plenty of room for improvement.

Make better decisions and fill your products with “Give a Damn”!

As his clarification states, while his comments may seem damning, they’re not necessarily related to any individual people he worked with, or decisions made above him. They’re more about his clear passion for the idea of optimisation itself, a structural and systemic issue that, at a company as big as Meta, might have been maddening for a guy used to writing code and firing rockets into space.


This would normally be the part of a story where I would drop some conjecture, maybe about how such a high-profile departure might spell trouble for Meta’s efforts in the space, but lol, I think Meta are doing a good enough job of shouting that from the rooftops themselves.
