The author's opinion of Rust being less is that, an opinion. It does have large advantages over C: memory safety, an incredibly powerful type system, a compiler that supports detailed error messages, a powerful build tool (Cargo), an expressive macro system, etc. Others who have built applications with Rust seem to be coming away with a much different impression that the author. He does mention some gaps (lack of a spec, unstable ABI) but these are not hardstops for all usecases. The main thread of complaints appear to be from lack of choice of tooling and compilers. I'd wager that the advantages outweigh the drawbacks for many projects, though not all.
