Yup. I think there's actually some good ideas in here, but then it's surrounded by ridiculous conclusions. For instance, I think deliberate practice is a good thing; you can quibble on the definition of that but fundamentally its true that people often plateau in their skills because they get comfortable and lack a growth mindset.

That's great, but then it says that in order to improve you need to declare a metric so you have something to measure, and then work to improve that. I don't even know where to begin with this; Goodhart's Law is the obvious response. But even more fundamentally than that, the thing that makes programming hard is entirely the qualitative aspects. Every single choice you make in software is a tradeoff with subtle implications, good software engineering is about understanding these tradeoffs in a given context over a period of time, there is absolutely no way you are going to reduce this to any kind of metric without throwing the baby and all its siblings out with the bathwater.
