Typescript is also far slower both in terms of runtime and compilation time, uses much more memory, and is far more complicated which in turn has led to a ton more compiler bugs. It also inherits a ton of questionable features and API decisions from Javascript and has a tiny standard library which means most Typescript developers repeatedly end up turning to the NPM ecosystem which is an unmitigated disaster. Deployment also isn't even remotely as simple and reliable as Go even with Deno compile.

I like Typescript a lot but the reality of Typescript development is not great.

This isn't super clearcut. Typescript has lots of footguns and famously says that soundness is not one of their driving factors. There are lots of ways to devolve to accidental implicit any's (even with the no implicit any strict rule turned on).

Of course, Go makes zero attempt to enforce nullability (nilability?) in its type system... so... win some, lose some I guess.

Any language based on JS can't be safer than Go. The end result of TS is JS which is a dynamic language.
