One of the reasons we have programming languages is they allow us to express fluently the specificity required to instruct a machine.

For very large projects, are we sure that English (or other natural languages) are actually a better/faster/cheaper way to express what we want to build? Even if we could guarantee fully-deterministic "compilation", would the specificity required not balloon the (e.g.) English out to well beyond what (e.g.) Java might need?

Writing code will become writing books? Still thinking through this, but I can't help but feel natural languages are still poorly suited and slower, especially for novel creations that don't have a well-understood (or "linguistically-abstracted") prior.
