technology is never just technology
So a thing you have to understand is that technology is never just technology. Technology is always material culture and material culture is always about signaling things, things like "I am a powerful and wealthy individual in my culture" or "my goods are high quality and well made" or "I'm just a little guy." Pottery is useful to archaeologists for dating things and identifying who lived at a site because pottery from different places and times is quite distinct; even after thousands of years, crockery never converged into an optimal efficient shape.
Throughout history, we will find examples of objects whose form follows not function, but a social performance that their owners were putting on. Take so-called 'dueling pistols' of the 19th century, most of which were actually intended for practical shooting (having sights or rifled barrels; accuracy is a no-no in actual pistol duels) but which are designed with the aesthetics of elite dueling in mind. Or the SUV of the early 21st century, an impractical and oversize town car that's meant to suggest the ruggedness and masculinity of the owner even though it is in no way a utility vehicle.
Anyway, that's why when the robots rebelled, there were all those household labor frames that were dressed up to look like military killbots. But don't be intimidated, rookie, it might look like ablative round-deflecting active armor but it's actually just fiberglass. Strap on your helmet and check your mags, we're just about to drop.
