I have written, and continue to write at another org, Go that drives line of business software that makes billions of dollars and runs the real world. Check a random email you have and if you see a header X-EID, it was processed with Go.

"Enterprise" traditionally refers to code that is full of bad practices. Like, when Java was all the rage, FooFactoryBuilderFactory was the embolism of enterprise. In other words, where sloppy developers are found. Glad we were able to clear up that isn't what you meant.

So you are meaning – with respect to the code – the same as all other software? What, then, is "enterprise" trying to add? It is not like you would write code that makes billions any differently than you would a code that makes a dollar.
