Yeah well, you're anonymous, so you might as well be someone with a huge ego who got their idea shut down by Carmack once and is still bitter about it. More often than not, when people think they "prove something wrong with data" it's more that they're "taking some data and interpret in a way that fits their standpoint". Carmack has proven enough times in the past that he's able to deliver, that he can push technolog…

>has proven enough times in the past Past experiences do not mean future success. This isn't even about Carmack: past 'heroes' end up failing in their decision-making in the future many times, and they were followed for no other reason than 'they have a track record'. The sooner that myth dies, the better.

Past experience is not a perfect predictor, but still much better than almost anything else. I'm pretty sure you'd feel safer going into an operations if the surgeon said "I've done this 100 times now" instead of "This is my first time with this procedure".

Of course, it matters if the experience is directly relevant, and that's where hero worshiping often gets it wrong.

”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…

He isn't alone. A core problem is that FB culture is way too positive and happy, and hard criticism is received poorly. The politics to get anything done if your name isn't Mark is borderline impossible. I left a year ago, and I've become beyond happy.

That is a problem in every company to be honest. And bigger problem as it gets bigger

Honestly no one really cares about VR that’s the problem. I feel like this is definitely the elephant in the room everybody is ignoring. Almost nobody gives a hoot about VR! I'm a software engineer with a lot of (surprise, surprise) nerdy/geeky/whatever friends and interest in VR is close to zero. A few friends vouched for various games like Half-Life:Alyx and Beat Saber, but nobody was claiming it was a life alterin…

I don't know about your friends, but playing Alyx opened my eyes to the level of immersion VR can achieve. It's a kind of gameplay that can't be repeated with 2d screens. I really do think it could be revolutionary, based on playing that game alone. If you can get ahold of a headset and a powerful gaming PC - I recommend giving it a try. The problems right now are very fundamental. The quest 2 out of the box is supre…

Disney World's Animal Kingdom has an Avatar-themed "ride" where you are linked to a banshee rider. And they make you wear these silly glasses, with thick, bulbous lenses.

So I'm there, mounted on a plastic motorbike, staring down in disbelief at the smaller-than-iPad display where the tachymeter and gauges would be. In front of me, in front of everyone to my left and right, is just plastic nothing. Plastic. And I think aloud, "Okay, are we gonna look down at this little screen the whole time?" The guy next to grins too: Where's the screen?

Then it starts. Holy crap. My entire field of vision is Pandora--up, down, left, right, everywhere.

And we are flying on banshees! I feel a moment of weightlessness as we careen down a canyon at the speed of gravity. I want to hoot and holler. It's pure joy, and my heart sings.

That's virtual reality, to me.

You’re definitely right the technology has tons of potential. Lots of applications in, for instance, content-creation space as well.

The problem Meta ran into is that it’s difficult/impossible to make money on it. It’s a niche market at best, and it’s much more difficult to prove the value when compared to something like Facebook. Facebook is easy to use and provides social value to everyone on the planet. And I say that not using it myself but I live in a small town and all business here rely on Facebook; the municipalities use it to communicate; elderly use it… it’s accessible.

I’m sure the wall Carmack ran into was the shareholders. To shareholders it’s more often than not about profits. To Carmack it’s probably about the product he envisions, not the profits. But you can’t have both sustainably when folks can live without VR.

I would jump on the bandwagon if my VR headset was mine: like a computer I can install whatever I want there—not in a walled garden owned by Evil Corp.

The proper VR solution needs to be open source hardware and software. By the people, for the people. Reduce the barrier to entry and people will use it.

One more thing: those virtual avatars are impossible to take seriously. If I’m in a virtual boardroom filled with those, I might as well be playing Minecraft.

> [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.]

as someone who spends a lot of time in a profiler, this resonates with me. the irony that i work in JS/TS is not lost on me, but most React apps make me sad, most node_modules make me sad. V8/JSC/SpiderMonkey are amazing JITs, and seeing them get bogged down by inefficient JS is painful. i see many devs jumping to Web Workers or even WASM when in fact their existing JS and algos can be orders of magnitude faster with just a tiny bit of forethought.

> it is the more personal pain of seeing a 5% GPU utilization number in production

yikes, is it that low?

I see a lot of negative comment on the other thread and on twitter so I feel the need to comment as well. It’d be great to get the perspective from someone who worked there, but I can offer mine as an outsider (worked on a different team at fb).

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.

Wow can definitely relate to this being in a high level IC position, but not having enough influence on management to change the direction of the company. You sit on the sidelines knowing a decision is wrong, and after having said your piece you watch it play out over years, turning out exactly as you expected it to.

Bah humbug.

I don’t really believe the line about Meta being the right place for it to happen. I think he very convincingly proved that it is indeed not so. Seems innovation does require some agile leadership, and not an entirely flat structure which feels a bit like steering a boat.

> I have no idea when "design by committee" became something to emulate.

When we renamed it with a catchy name: Agile. The Manifesto's entire deal is highlighting the key considerations an organization must take into account if they want to move to a flat organizational structure.
