I think an isolated and ambiguous sentence like the one you provided with zero surrounding context is perhaps a bad example. English can be very ambiguous. It is also possible to write unambiguous English, as far as deciphering intention is concerned. I think LLMs have shown us just how far English can go as a medium to get quite good results. And as others mention, there are other tools, like compiled programming languages and static analysis tools and unit tests, that can do more of the heavy lifting on our behalf.
