#4How Fuchsia is compared to L4?

#5We know Google has its own CPU made from scratch, now new OS... is Google creating new end-to-end solution for desktop/mobile? With completely new hardware and software on it?

#6One wonders if Fuchsia is one of those '20% time' projects, where a single (or group) of Googlers get to spend 20% of their work time on a personal side-project.
Even if not, I'm also thinking that if the roadmap here is for a drop-in replacement OS for the AI inside Google cars - don't they currently run a variant of Linux? Which as the fastcompany article says, isn't an RTOS.

CPU from scratch?
Are you referring to the LLVM backend for a "new" lanai ISA that they contributed recently? That wasn't designed by Google (but an existing networking equipment manufacturer) and it wasn't a general purpose CPU (integer only, no hardware dividers, made for running a TCP/IP stack and not much else).
This new kernel/OS is a bit more interesting than that. This seems to be targeted at end user devices, runs on x86 and ARM and has got some kind of userspace with UI going on.
It would be interesting to know what this is targeted at.

#8Shouldn't it be "Micro kernel written in C++" ?

Yes, I'm referring to what was described in this thread https://news.ycombinator.com/item?id=11072085

#10Shouldn't it be "Micro kernel written in C++" ?
Github says the code is 72.6% C and 19.3% C++.
Personally, I wouldn't call that 'definitely C' or 'definitely C++'
The Linux kernel, just for reference, is 95.7% C and only 2% C++
