> If you are writing a sales tax calculator and need to implement 500 different local state sales tax regulations from a scanned Word document, your best developer is going to be maybe twice as fast as your average one.

This isn’t software development. It’s mostly translating a scanned document into data. If you leave that task to a non-developer (because it isn’t development-related), I’m convinced you can see a 10x difference in productivity for the remaining work (writing the actual software).
