I disagree. There are plenty of design decisions in Go that make it less optimal for very large projects (e.g. dependencies, error handling, generics), but most of all lack of hackability. Go is one of the least hackable languages I've ever encountered, i.e. the only escape-hatch you have when you realize, 5 years into the project, that you need to circumvent some runtime semantics are either source-code instrumentation or hacking on the runtime itself.

There is no way Go's GC wouldn't crap out on you sooner (except maybe in the circumstances that are now addressed as part of Valhalla).
Having said that, I think Go is great, and is a natural fit for anyone who likes the Java philosophy (which is also the Go philosophy)[1]. Some design decisions and some implementation circumstances just make it less suitable for really big stuff.
[1]: Namely, reading comes before writing, no too-clever tricks, and no cutting-edge PL ideas; a "blue collar" language, as Gosling referred to it.
