Most of my "favorited" comments on here are by software people with confident yet incorrect statements (usually by way of vastly underestimating complexity) about one of my domains of expertise.
I can't find it but one of the greatest show HN was a blog post about someone who was annoyed by his inconsistent shower temperature control. From memory, he spent a full weekend adjusting it, taking measurements, making graphs, and proposed "next steps" about prototyping better temperature control with microcontrollers and servo and pontificated about developing a product, of course controlled by software. He skipped the part where a bit of research leads you to the already common "thermostatic mixing valve".
In a community largely made of people whose job it is to produce such functions, I'd say it's to be expected
