Anything you create in 2018 will look like something created in 2018 since you cannot move into the future to compare.
Use Star Trek as an example. For some reason the weapons they used looked like guns. They could fragment into molecules and be reproduced aboard a ship with everything intact, but they had a shuttle that looked like a cargo van and big incandescent indicators that flashed (in sequence, per Shatner).
FFWD to today's verson. The Enterprise looks different inside and out. It doesn't look like the future, it looks like right now. We don't know what the future looks like.
It'll look weirder than we can imagine, probably. My guess is interstellar spaceships will have NO aerodynamic qualities for quite some time. Shipyarded in space, stay in space. Probably for millennia.
