How many civil engineers or architects know how to put up scaffolding or lay bricks?

That was a little tongue in cheek, but I am genuinely curious what you think the correct approach is? I have seen many teams that do need to have someone overseeing the overall architecture, even if that person isn't writing the code line-by-line.

If you have that capacity baked into "Backend Programmer", then great, but not every team is the same.

Is there something inherently wrong with an "architect" who hasn't written code in a decade but is instructing seniors? One might believe that the answer is self-evident, however, I would argue that the organisational structures we see in the world (functional or otherwise) do not bear this out.
