Swift is 5 years old and yields more results then rust who is 8 years old. You know you have a good one when it picks up and just goes. All of them 3, poor Rust is the most talked about in HN and yet is the least used in real world.
As for upwork skewing, you really have no idea what upwork is. They have absolutely zero interest to hide results as their money comes from those jobs people get hired for. So why would they cut their own revenue?
It's not about Upwork intentionally skewing the results as you pointed out, but that there is a potentially sampling bias. Upwork might only attract certain kinds of programming jobs and those are less likely to use Go and Rust.
Except it doesn't work like that at all. In there you have real problems from real people who want the job done. If their problem requires Rust, then trust me, they will ask for Rust. And those are the people who pay the freelancers. As a freelancer I have zero saying in what clients want, I am there to help with their problems, not for them to bow before my choice of programming languages.
Rust inspired Swift heavily. I kinda don't care about Google results. All the big companies are doing something with Rust. Microsoft is doing actix and wants to use rust for IOT, Apple is trying to make Swift more like Rust, Google supports Rust on Fuchsia as a first class language etc.
I didn't say that upwork is skewing it intentionally, I'm saying that the samples aren't representative of the larger population.
And as a freelancer I don't care what company X or company Y does internally. I care only about the jobs I can get. When enough of them will start having problems in Rust and start posting jobs for outside world then maybe I will care about Rust too.
Yeah, I know, I'm an a*hole for not loving Rust from 1st second, sorry for caring about my family first and not enough about Rust. </sarcasm>
