I'm thinking that technology evolves from designs that take their cue from function, which then become refined and eventually free from the underlying tech. We see spacecraft today that are dominated entirely by crushing limitations on takeoff weight and limits on power sources and life support. In the future we have in Traveller, those limitations are long swept away.
Potentially we might see space craft that become style and fashion statements, and that look becomes the retro.
This is why I've argued for years that materials technology advancements should allow auto manufacturers to bring back fins, bullet-bra bumpers, and sweeping fenders. Technological should help advance style in design.
