However, don’t underestimate the long-term benefits of Rust

I think the author is underestimating the long term issues with Rust. Its already the case the language and ecosystem is so much in flux that code that's been written today has been made obsolete by a language feature in the latest nightly build. Rust is risking of going the C++ way: have some many freatures bolted on that even as an experienced developer, you can checkout a random project on Github and discover a new language feature. That is not a good situation for projects that require longevity, especially in a professional setting. When working on software in a professional setting, you will often have cases where you revisit code bases that you have not touched for half a year. You will have a hard enough time to stitch your thoughts on how your business cases worked back together. You really don't need syntax patterns that you haven't seen in half a year to get on your way.

Using Rust for projects with a long lifespan requires something from developers that we are especially bad at: the ability to be disciplined when presented with new, shiny things. Go on the other hand has this by design, which makes it admittedly boring but also relieves you of such burdens so you can focus more on getting things done.
