You're dramatizing the mental overhead needed to not write semicolons. Every serious project uses a linter that can add or remove them based on some flag. I don't use semicolons. It's an unnecessary character. Life moves on. I'd say Rust has worst of both worlds, if you want to compare it to something, where having or not having a semicolon can mean two different things (return the value or return void). That's an example of actual mental overhead that semicolons can create that still bites me after more than a year of Rust. And it's not something that tooling can necessarily fix for you unlike Javascript ASI. Using semicolons in Javascript just to keep my brain trained for semicolons in other languages is probably the worst reason to use them I've heard yet. And every time someone finds out I don't use semicolons in IRC, they seem angry about it. So I wonder how much I avoid semicolons just for the sport of it, now.
