Okay - could you give some examples of where you think huge advances in software have been made?
Not OP but eBPF, Android ( phone, TV, auto) and iOS, ChromeOS, VS Code, Go, Swift, Powershell ( it's a terrible piece of software but a vast improvement for Windows), virtualisation, public cloud platforms ( virtualisation at huge scale with APIs), the Hashicorp stack, ZFS, LXC and later Docker, Kubernetes, Redis.
Hardware and software are closely intertwined. We couldn't design, develop, build, and run modern hardware without modern software packages. You're just not seeing the advances in software if you're only looking at famous web services technologies.
The whole article is extremely myopic, limited only to the author's narrow domain of web services and coding in text editors.
