WebGPU is a textbook case of Embrace Extend Extinguish performed by Apple to kill Kronos and SPIRV, and everybody is cheering it on. Crazy.

The WebGPU spec is currently edited by two Google employees and one Mozilla employee. I am not sure how to make sense of your accusation.
Still doesn't make any sense but it has nothing to do with who the editors are.
WebGPU, all the bare metal crashes/exploits and none of the broad support. Browsers should not be operating systems and the move to make them so will end up making them just as exploitable as your host OS only much slower due to the additional abstraction layers.
Now, sure, there must be plenty of memory-safety issues in GPU drivers, but why find an exploit in a driver only some users have installed, when you can find an exploit in the browser everyone has installed? The GPU driver exploit doesn't give you higher privileges.

Am I understanding this right, that websites can now run a crypto miner in the background when I visit them?
The people sneaking this shit into webpages don't care if it burns $1 of electricity and destroys your battery to generate $0.0000001 of Monero because all of those costs are paid by someone else.
Earlier quoted context omitted.
It's already the case. Any web page can use WebGL1/2 for general computation. As the author said: > Using GPUs for calculations of any kind is often called General-Purpose GPU or GPGPU, and WebGL 1 is not great at this. If you wanted to process arbitrary data on the GPU, you have to encode it as a texture, decode it in a shader, do your calculations and then re-encode the result as a texture. WebGL 2 made this a lot…
True, but this API will make that use case simple and obvious. Given the tradeoffs, probably worth it for user agents to permission-gate it.
Question for someone with gpu programming experience: is it feasible to analyze time series data (eg.: run a trading algorithm through a series of stock prices) in parallel (with the algorithms receiving different parameters in each core)? If not then what is the limiting factor?
This depends on the algorithm. If it has lots of branching and control flow, then it's unlikely to run well. If it's based on something like FFT or any sort of linear algebra really, then it should run really well. WebGPU is accessible enough maybe you should try it! You'll learn a lot either way, and it can be fun.

Already a thing, it's just been CPU based and now can be GPU based. Firefox (and probably other browsers) have systems to attempt to block them. https://blog.mozilla.org/futurereleases/2019/04/09/protectio...

For those interested, I was only able to get the demos running in Chrome Canary with "Unsafe WebGPU" enabled.
