John Carmack's arguments against building a custom XR OS at Meta

> They also got me reported to HR by the manager of the XROS effort for supposedly making his team members feel bad

I've only seen John Carmack's public interactions, but they've all been professional and kind.

It's depressing to imagine HR getting involved because someone's feelings had been hurt by an objective discussion from a person like John Carmack.

I'm having flashbacks to the times in my career when coworkers tried to weaponize HR to push their agenda. Every effort was eventually dismissed by HR, but there is a chilling effect on everyone when you realize that someone at the company is trying to put your job at stake because they didn't like something you said. The next time around, the people targeted are much more hesitant to speak up.

I followed his posts internally before he left. He was strict about resource waste. Hand tracking would break constantly and he brought metrics to his posts. His whole point was that Apple has hardware nailed down and it’ll be efficient software that will be the differentiator. The bloat at Meta was the result of empire building.

I remember watching Carmack at a convention 15 years ago. He took a short sabbatical and came back with ID Tech 3 on an iPhone, and it still looks amazing well over a decade later.

This is a guy who figures that what he wants to do most with his 3 free weekends is to port his latest, greatest engine to a Cortex-A8. Leading corporate strategy? Maybe not. But Carmack on efficiency? Just do it.

Impressive. JC is always one of the engineers I look up to and read up to when depressed.

John Carmack, David Cutler, Tom West, Cameron Zwarich, etc. There are about maybe 50 of them.

Carmack and Jim Keller for me. Hardware engineering for the latter!

Where are the good war stories on Keller?
