The first half of the sentence you quoted is "even if you do everything right". What is the point of selectively quoting like that and then responding to something you know they didn't mean?
With respect, the first half of the sentence sounds more like waffling than a clear warning to your peers. I bond with other engineers over how badly the industry as a whole handles the scientific method. Too many of us can’t test a thesis to the satisfaction of others. Hunches, speculation, and confidently incorrect. Every goddamn day.

That’s a lot more than 1/10, and he’s talking mostly to future scientists, not developers.
