What an odd things to say about software engineering... where your job is literally writing. Like telling a newspaper reporter that to get better at their job they should write more. I mean who would have thought that practicing your craft would improve it.
I know the author here is talking about non-code writing but it still sounds weird to hear it given that is our job. To write. I call myself a writer when people ask what I do as it represents it much better than any of the dumb technical names people have come up with. No I don't build houses nor do I design physical artifacts. I write.
