Are you a member of a team? Then you are the outsourced intelligence. Your manager is not writing everything by hand, they are outsourcing it to you. Just understand that may change (I mean I am already mentally prepared for it to be a thing of the past within years). If you are purely writing software for hobby/fun then disregard, nothing will stop you from doing that.

I have no problem with other people outsourcing their intelligence to me, I've been doing this for years. But I prefer not to outsource my intelligence, at least not for things I care about, for various reasons.
