I disagree pretty strongly with this claim. Nine years ago we didn't have (or they were in their infancy): Rust, Go, TypeScript, GitLab, VSCode, Language Servers, American Fuzzy Lop, Linux distributions that work out of the box on most hardware, web "standards" that are actually standards, ...
I would argue that all of these have dramatically improved software quality, and the software ecosystem as a whole. The industry is unrecognizable compared to a decade ago, and almost all changes have been for the better.
