Sorry, should have been clearer - butter robot from Rick and Morty. An entity who has one menial job to do and that is the reason for their existence.
In this sense it was meant that the technological solution - auto documenter tools, etc - they're the butter robots. I was making the point that rather than just shim Yet Another Tool into the stack to do a single but important job (pass the butter / write the docs) perhaps give it to a human who will a) do a much better job and b) reduce the complexity of the stack.
Apologies for the confusion.
I'm surprised how this comment thread took off. Looks like there's plenty of support for AND against. I simply meant to make the point that for some problems humans do better than machines and it can be more efficient in the long term to look away from a tech solution to a human problem.
