I’ve worked in C++ and picked my own tools. The tooling experience in Go is much more polished for a few reasons.

First, as the author states, it’s hard to get consensus on a tool if it wasn’t baked in from the beginning. I don’t think there will ever be a dependency manager or especially an option-free formatter for C++ with the same adoption as gofmt or go modules.

Second, it helps a lot to have the compiler/runtime authors think about the tooling. Go runtime developers think about pprof. GCC developers don’t think about the UX of valgrind. C++ standard authors don’t write PR’s for code formatting tools when they change the language spec.
