The fearmongering here is growing to new heights. If managed properly each application that runs in your browser could have its own directory to work in, without being able to write anywhere else. Just because you don't understand what this new technology is all about, doesn't mean it's as scary as some make it sound.
Being able to run any program in your browser, no matter the device or operating system, given your hardware is powerful enough, is going to make software much more accessible than it has ever been. If it works and it supports DirectX and Vulkan, Steam will immediately migrate to this new API, finally achieving Valve's goal to be platform independant.
