Android Open Source Project Now Includes the Fuchsia SDK and a Fuchsia ‘device’

I want to be sold on Fuchsia/want it to succeed because of security. If it succeeds the UI will change a bunch of times, and there will be many UIs.

Very happy to be corrected, but it seems to be the best hope since Midori was canned, and Fuchsia has the great advantage of being open source. By the way, I've casually looked for but not yet found a comparison of Midori and Fuchsia approaches based on what is known about each, maybe following structure of posts in http://joeduffyblog.com/2015/11/03/blogging-about-midori/ ... I would love to read that!

This is probably off-topic, but AFAIK “the uncanny valley” refers specifically to artificial representations of humans looking “too much but not quite enough” like real humans. I’m not sure how UI elements (which don’t typically depict humans) would fall into it.

I think you're confusing fuchsia and flutter. Fuchsia is a new OS while flutter is it's native UI. I don't think "uncanny" is applicable here.

I always thought the current UI was designed to test out the core frameworks rather than something they would ship to consumers/users.

Fuchsia was started before Rust 1.0, and you still can't do OS dev on stable. It would have been cool, but I also don't think they inherently made the wrong choice.

That said, there's a few hundred thousands of lines of Rust in there, and more on the way. The Fuchsia team also lets some of its team contribute back to Rust development, which is far more support than having the kernel part of a microkernel be in the language, IMO. (You can see this in Futures and async/await, which Fuchsia makes heavy use of, and the team has been very helpful in driving the design and implementation to completion.)

Although the majority of Fuchsia was written in C++, some of it does include Rust[0].
