Developers should get promoted but in a way that they don’t forget the difference between bit and byte. This means that a developer should be promoted to Senior Developer then to Architect then to Enterprise Architect etc. I don't see what the 'etc.' could be, exactly, without being a manager. Even the title "Enterprise Architect" sounds like a stretch to me. The article's point may be valid, but the solution proposed is very vague.
