This sort of comment is not really relevant to the article that was posted, which is not about Go's type system, or convincing TypeScript users to switch to Go. I'm sorry that you don't like Go's types, but I'm going to guess it's not really targeted at your needs if you are a TS user.

It's okay not to use Go for your projects. But there's no need to drop your personal opinion of a language into a post about specific case studies of how that language is used inside a company.
