Even in the first paragraph the author goes into some nuance about what they mean and it's not at all what you're saying? Years ago, I'd work on one or two things at a time. Now I do maybe 10+ things in parallel. I work more hours, "let me just finish up this one thing" I'll say, and I look at the clock and it's later than I thought. At the end of the day, my brain is cooked. Right now I'm motivated by the novelty of this new tool that gives me superhuman productivity, but a few years from now when that novelty has worn off? Well, probably a few years from now we won't have software in any recognizable sense anyway, so maybe it's not worth thinking about.
