The issue is, it's likely that a company with $2 BILLION spent on product development and a very deep relationship with Apple, like Unity, will have success using WebGPU the way it is intended, and nobody else will. So then, in conclusion, WebGPU is designed for Unity, not you and me. Unity is designed for you and me. Are you getting it?

Not really. Bevy https://bevyengine.org uses WebGPU exclusively, and we have unfortunately little funding - definitely not $2 billion. A lot of the stuff proposed in the article (bindless, 64-bit atomics, etc) is stuff we (and others) proposed :)
If anything, WebGPU the spec could really use _more_ funding and developer time from experienced graphics developers.
I agree with you, Bevy is a worthy cause.
Why are people downvoting? The idea of Great High Performance Graphics Effortlessly on All Platforms is very appealing. It is fundamentally empathetic. It is an opium to game developers whose real antagonist is Apple and Nintendo, and who want a more organic journey in game development than Unity Learn. Is it a realizable goal? Time will tell.
Everyone should be advocating for more focused efforts, but then. Are you going to say, Bevy is better than Godot? It’s subjective right? Open source efforts are already spread so thin. An inability to rally behind one engine means achieving 2013’s Unity 5 level of functionality is years away.
Looking at it critically, in fact much effort in the open source ecosystem is even anti games. For example emulators used to pirate Nintendo Switch games have more mature multiplatform graphics engine implementations than Godot and Bevy do. It would be nice if that weren’t true, you might tell me in some sense that I am wrong, but c’mon. It’s crazy how much community effort goes into piracy compared to the stuff that would sincerely benefit game developers.
WebGPU is authored by giant media companies, and will have purposefully hobbled support by the most obnoxious of them all, Apple - the one platform where it is kind of impractical to pirate stuff, but also, where it is kind of impractical to deliver games through the browser. Precisely because of the empathetic, yet ultimately false, promises of WebGPU.
Why are you bringing up Godot again? Are you worried Godot will be left behind or unable to compete with Unity? Are you working on Godot? Why are you focused exclusively on games? What are the ‘false promises’ of WebGPU, and why do you think it won’t deliver compute shaders to every browser that supports it, like it says? I’m just curious, I get the sense there’s an underlying issue you feel strongly about and a set of assumptions that you’re not stating here. I don’t have a lot invested in whether WebGPU is adopted by everyone, and I’m trying to understand if and why you do. Seems like compute shaders in the browser will have a lot of interest considering the wild success of CUDA. Are you against people having access to compute shaders in the browser?

It seems like you’ve jumped to and are stuck on a conclusion that isn’t really supported, somewhat ignoring people from multiple companies in this thread who are actively using WebGPU, and it’s not clear what you want to have happen or why. Do you want WebGPU development to stop? Do you want Apple to support it? What outcome are you advocating for?
Unity spends the vast majority of its money on other things, and Unity isn’t the only company that will make use of WebGPU. Saying nobody will have success with it is like saying nobody will succeed at using CUDA. We’re just talking about compute shaders. What is making you think they’re too hard to use without Apple’s help?
You haven't substantiated why nobody else could make use of WebGPU. Are Google the only ones who can understand Beacons because they make $300B/year? GPU is hard, but it doesn't take billions to figure out.
There are already open source projects making use of WebGPU, e.g. wgpu.
