Mmmm... We'll just have to disagree on this. I can track a great number of octaves, from business strategy down to operating system scheduling and locking strategies, CPU instruction pipelines and scheduling, semiconductor fabrication techniques, and even down to the lifetime exergy of the whole equipment/software/facilities supply chain. But I can only do a little bit at a time, an as-needed basis. I can't be too concerned with instruction set design or supply chains while I'm optimizing an SQL query or building a D3.js web visualization. It's just too remote from the task at hand. If you, in contrast, can simultaneously understand and reason about every technology along the continuum from delivered apps and services down to the impedance constraints in the CPU layout process, good show! That's a surpassingly rare skill, but perhaps there are some Sherlocks among us.
