“Would aliens also have X?” for almost any X tickles the brain a lot.
The X that primed it for me just now (again) is stainless steel, but almost any generalization of it works.
Does feel like the right way to rate the progress of a species is material technology!
Alien species prob relied on stainless steel during a brief phase of their existence? Humans have only had it for a small fraction and will likely move beyond it in time?
Great material tho!
If they have enough iron/carbon/chromium/++, and live around solids not float in air/water, and have oxygen+water around for “stainless” to make sense, and didn’t go some weird “zerg” tech route, and aren’t in otherwise extreme environments, and build structures at all, and... ;\
I wonder if an undersea sapient tool-using species (maybe something octopus-like) would find a way to smelt metal? There's stuff that burns underwater.
