So that's neat, but not what I was saying.

This is completely the wrong way to think about division of labour.

We started to figure this out 300 years ago for god's sake.

It's not helpful think about our tasks as a series of bits of work to be accomplished that we hire spigot-workers to do. White collar work is mostly not labour in that sense.

Thinking about your organization like a CPU doing calculations is utterly the wrong analogy.

More like band, playing a song - most tasks have some level of optimal participation you don't want to be below or over, and/or it might be incrementally harder to improve quality depending on variables. And 'talent' usually matters more than anything.
