Very much agreed. Beyond that there is the tooling around a language (besides just the compiler): debuggers, IDEs, static analysis, memory analyzers, decompilers, performance analyzers, etc. Each of these help during specific parts of a programmer's job. The article focused on the language + compiler, but much of the infrastructure around a language is hugely important in how much time different parts of the job take.
