There is a fairly widespread feeling that webGL is evil and a road that should not be gone down. I tend to agree as it means browser client code is diving into low level drivers to access OpenGL. However 'serious' graphics work with HTML5 is stuck at the moment with a 2D canvas and no real access to GPU acceleration. I'd love to have native 3D access in HTML5, then I could get rid of Flash, but Flash allows me to write shaders for the GPU to get performance.
The webGL Earth demo is still pretty smart though!
