I don't know why but I'm actually less excited about Fuchsia than the old Singularity/Midori. As Joe Duffy said [0] when they worked on Midori they also wrote UI, editors, browsers and many more applications in months so it's not surprising Google engineers also managed that.

For me it looks like the classic Not Invented Here syndrome - we already have microkernels, even formally verified ones (seL4) but AFAIK Google didn't want that to "be more flexible".

Using C for kernel also looks like a poor choice nowadays, unless Google has some magic static analysis (for example Singularity/Midori had custom languages with ownership tracking akin to Rust).

Maybe Fuchsia is for bringing microkernel architecture for masses using "boring technology"?
