Yeah, we were segueing into hard sci-fi and the real future here, so I’d thought I’d bring that up. OP was about this tendency in general.

In soft sci-fi you can just handwave stuff, with the basic way frames of reference work being a frequent casualty (via FTL travel). If traveling by starship is like traveling by boat, it makes sense day-to-day life would be a bit boat-like, and so that’s where many writers have gone.
