My response was more doubting that Go is going to be used many times more than it is currently 10 years down the line, but the trend on Rust is upwards:
That doesn't mean it will ever achieve popularity, and could also go away.
However, with the Go developers' insistence on changing the language as little as possible (not good or bad, it just is), it seems unlikely that Go will see a resurgence that brings it to multiple times usage than it has now.
But, they are working toward Go2. Generics, which are the biggest talking point whenever Go is discussed, is already added in a branch and is supposed to come in a year or so. It'll be interesting to see how it'll affect the trends data after that.
Not really because the difference is that the overall trend on Rust is still upwards (it's hard to see with the two languages on the same axis). I've been investigating Rust and it looks like it's going to cure the pain points I've had around C++ on a project I'm working on and I'm quite happy with it so far.
