His point is to use whatever simplifies workflow / reduces operational overhead. To some people, that indeed would be k8s. To you, that may be "managing a couple of webservers and a db". And that is great for you.

yeah I use k8s for basic webapps and it works wonderfully, and is way way easier than anything else, and yes I started developing in the 90s so I've seen it all. There is a bit of overhead in learning k8s, but once you know it, it's dead simple for every use case I've found and takes you way further than anything else.
