Sigh. Looks like it's time for round 5 of time to learn Rust(my personal failing, not meant as a slight against the language at all). Has the pace of sweeping changes to the language slowed down in the past year? I rode the Ember train from 1.4 to now and it was an extremely ehausting process to get to 2.0 with nearly every version requiring frustrating architectural rewrites. The upgrade from 2.0 to 2.8 took like 15…
I started trying to learn Rust at 0.7 (maybe a bit earlier, I can only find references to 0.7 in a few projects of mine). Boy howdy did that feel like an exercise in futility. I would set it aside for 3 weeks, revisit it, and find entire language constructs had been removed. I complained about this and Steve Klabnik graciously reminded me that it was a work in progress and that the work was being done out in the open intentionally. I really can't thank him enough for that since it caused me to go from frustrated to sympathetic. As a result I decided to not write the language off. And I'm glad I didn't. After things slowed down around the betas for 1.0 it became clear that Rust was worth learning. I haven't had a chance to use it professionally, but for personal projects I find myself reaching for Rust for problems that would have caused me to have reached for C in the past.
Also, Google has gotten significantly better about returning current and up to date information on Rust as well. Around 2013-2014 my biggest gripe was that I'd search for how to do something only to find advice that was woefully out of date. I haven't had that experience in well over a year now.
