cto is a very wide title and in a global enterprise with hundreds of thousands of employees it's impossible to have a flat organization. There's probably 15 vp of engineering reporting to the cto. Each vp is going to have 10-20 directors reporting to them and beneath directors the fanout gets even wider. It does incentivize busy work and in a large org you can hide in the corner and be a potted plant for your whole career if you're smart enough to find it. But that is the nature of a large cooperation, I can't remember who said it but something like 80% of impact and progress to keep a business going is made by 20% of employees whether it's a big company or not. The rest are just sort of there playing along.
