Go concrete. In FAANG engineering jobs now what % is this factory designer category vs what % is writing some mundane glue code, moving data around in CRUD calls, or putting in a monitoring metric etc?

Once you look at the present engineering org compositions see what's the error in thinking.

There are other analogy issues in your response which I won't nitpick
