Wow! You weren't kidding about GAIA's predilection for animal morphologies! Sure, not totally unexpected given the rough natural terrain her bots will have to navigate, but I agree that there's something deeper going on here. Her designs aren't just functional. They feel almost like, well, "tributes" is the word that comes to mind. As though she's already mourning their loss. And not just for the disappearing fauna of our time, but creatures from the fossil record, too - references to megafauna in some of her designs. So cool!
Well, whatever GAIA thinks up, HEPHAESTUS will empower her to build it. I just wish we could still be around in a century or two to see what she makes!
