Blog post author here: True. But there's no reason not to write when you are in anger about other languages that you do use every single day.
I guess I was just venting and also reaffirming my intention to use CL. I have used it before in a previous job for a quick tool and I know it can be used for more complex stuff, which I have already started building.
I haven't been writing a major piece of software in Lisp for 10 years, so I can't write about that. But I can compare how it feels to write software in other languages vs Common Lisp.
And also, Lisp is a blip compared to Rust or Go right now, so I don't know why it's so terrible to talk about it. People will keep talking about the things they like as much as the things they don't like. And it's fine.
