I get the overall point, but this humility makes it difficult to use some kind of grading/levels. Take e.g. MS Office as an example of a large C++ project. Certainly, there are developers with just "average" knowledge of C++ working there. Then there are people having strong/advanced C++ knowledge. But in a project like MS Office there are certainly devs who are still much stronger in the language, best in the project/company, but still likely below people like Stroustoup or Alexandrescu. How to call those? I think avoiding the term "expert" just to be consistent with the above-mentioned humility is impractical.
