Are you saying that technical standards are lowered as one moves up the IC ladder? If so, how and why?
There are programmers and senior programmers, data designers and senior etc. There are also team leads and program managers. There's basically two tracks, you either create stuff or you manage the creation of it.
They have different titles now, and there's a lot of Agile fluff (how is a scrum master not just a secretarial service and the function of a team leader not to keep their meetings focused?)
