> Though coding all day sounds very appealing, most of software development time is spent on communicating with other people or other admin work instead of just writing code

This sounds very...big corp, which inevitably needs many professional box drawers, expert negotiators, smooth communicators, miracle alignment workers, and etc. But guess what, if you are in a core group in a small company, you function as a grad student: you tackle hard problems, you spend time discussing insights, you derive theories, and you spend most of your time writing software, be it requirement gathering, designing, code writing, debugging, or documenting. But you definitely don't and shouldn't spend most of your time talking to other teams.
