I think people have forgotten about Google Fuchsia which I guess is a good sign for a new OS. They’ve done quite well in deploying it seamlessly to their consumer devices.

The reviews I've seen of its stability and usefulness have not been good.

Yup it’s because they had to rewrite the drivers I presume. Always going to be the biggest issue with any new OS.

That was also frustrating in that sel4 was right there. Why not invest efforts in the existing thing?

The microkernel core isn't the buggy/hard part; Fuscia's got a similar microkernel that also works great. It's everything else that's hard.
