Maintenance is a big win for Go imho - that you can go to code you wrote a year or more ago - and jump right back into it, with little-to-no re-learning curve. The syntax is not providing cover for complexity bombs, and the tools keep the workflow simple and quick.

How is it with Rust ? Does one's own old code remain maintainable ?
