> but none of it should feel like politics to your typical "I hate politics" engineer [...] Who doesn't like to share the cool stuff they've done?

Certainly many would prefer to just enter flow state and work on their craft, work the wood with the chisel (=do the engineering work), etc. It is of course not a good strategy in reality, and it doesn't matter what people "want", but let's at least admit that plenty of people don't enjoy having to interact a lot. People-oriented vs thing-oriented.

I know that plenty of people don't like doing presentations and writeups and such, but just telling your coworkers about whatever cool thing you've done seems to be pretty much universally enjoyed in my experience.
