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

John describes exactly what I'd like someone to build:

"To make something really different, and not get drawn into the gravity well of existing solutions, you practically need an isolated monastic order of computer engineers."

As a thought experiment:

* Pick a place where cost-of-living is $200/month

* Set up a village which is very livable. Fresh air. Healthy food. Good schools. More-or-less for the cost that someone rich can sponsor without too much sweat.

* Drop a load of computers with little to no software, and little to no internet

* Try reinventing the computing universe from scratch.

Patience is the key. It'd take decades.

Love this idea and wondering where that low cost of living place would be. But genuinely asking;

What problem are we trying to solve that is not possible right now? Do we start from hardware at the CPU ?

I remember one of an ex Intel engineer once said, you could learn about all the decisions which makes modern ISA and CPU uArch design, along with GPU and how it all works together, by the time you have done all that and could implement a truly better version from a clean sheet, you are already close to retiring .

And that is assuming you have the professional opportunity to learn about all these, implementation , fail and make mistakes and relearn etc.

Software is bloated and unreliable. It's clearly a "local minimum".
