Do you have a 15 seconds explanation on how that's going to be much better than WebGL?
While both of those APIs offer nearly full programmability, they do so with an API structure that retains a ton of legacy cruft from the days of fixed-function pipelines. Neither are low-level graphics APIs; many assumptions are made. This makes doing general purpose compute tasks on WebGL extremely hacky at best.
Think of WebGPU as Vulkan or Metal for the web. Lower level with much more work, but ultimately cleaner with superior performance and capability.
So this means that we'll soon have web ads mining bitcoins using our GPUs, right? :)
Can't tell if they are "honest" people who closed shop when they realized how bad their idea was, or if they just threw smoke and went dark.
