I may be overly paranoid, but the majority of what Fuscia is trying to accomplish is extremely bad for open platforms.

The outcome of moving drivers to user space will be proliferation of binary blobs and black box drivers. If you think binary GPU drivers are bad now, imagine an "open source" OS where every single driver is a binary blob. It will become impossible to run Fuscia devices on any other operating system because you have no drivers, sealing off the Android platform permanently.
