It seems like they all tend to break down but cooking is ok for some parts.
To that end I see these conversations as
"never use stainless steel to cook a hamburger"
"never use cast iron on a food truck"
"Always use an crock pot for soup"
Especially for startups it just doesn't matter that much. Use whatever you know how to cook with. If your DevOps guy can deploy kubernetes into AWS managed with GitOps designed by GitHub copilot and ChatGPT in terraform in 40 minutes and manage without waking up in the middle of the night...that's fine.
Or if you have a die hard linux admin who wants to buy servers on eBay and host them in the basement and do hardware updates at 2am...that's also really fine.
Stackoverflow literally uses windows servers.
These are all just different methods of cooking. Sure we each kind of prefer our way and insist it makes the food come out best, and sure there is truth to that at a point - infra does eventually wind up mattering.
But mostly we're just nerds arguing about what brand of chef's knife we use and that sort of thing.
