I keep waiting to see ambitious webgames that could match the experience of Infinity Blade from 2010, used to demo iOS new OpenGL ES 3.0 capabilities, the foundation of WebGL 2.0.

The only thing I like in Web 3D APIs, is that outside middleware engines, they are the only mainstream 3D APIs designed with managed languages in mind, instead of after the fact bindings.

Still waiting for something like RenderDoc on the respective browser developer tools, we never got anything better than SpectorJS.

It isn't even printf debugging, rather pixel colour debugging.

They’re also the only 3D APIs designed to safely untrusted code to use your GPU.

Assuming proper drivers, which browser black lists prove otherwise.

Hence one of the reasons why it never took off as Flash replacement, and indies rather focused on native mobile games.

It is hard to sell an experience, when there is zero control over the hardware acceleration.
