10% futuristic, 90% conventional

While we're on the topic of word choices...

As we saw in the first lesson, this snippet is both awesomely futuristic and science-fictiony, and completely ordinary. 

Lucky is describing Leo Five, a bustling and vibrant planet, completely different to his podunk moon home.

But let’s make a couple of tiny word substitutions.

They came in to Leo Five out of the midday sun. Around them, cars flowed in and out in orderly lines, their bodies gleaming in the golden light. On the radio, they could hear news stations full of chatter; the crackle and buzz of communications; the non-stop whirl of activity in the city ahead.

It was a relief to get going. After everything Lucky had been through, it felt good to breathe fresh air again; to feel wind on his skin, and sunlight on his face. He drank in the sights and sounds eagerly, relishing his first new city.

And Leo Five looked dazzling. The streets were drenched in rich golden light, and lined with tall buildings all lit up from within. Between them, the skyline was spiked by countless cranes, building even bigger structures. Words and pictures scrolled across their walls. Advertisements flashed by on enormous displays, faster than Lucky could read. Cycles and mopeds whooshed past them as they drove, an electric blur of motion, their lights like one continuous stream of flame.

This was the height of Human wealth, and it made the town where he’d grown up look like a toy town. It was astonishing to see all that energy burning in those buildings, powering this civilization.

So this passage is describing a planet—a whole planet!—but with a couple of word swaps we can see it’s really describing a city, and a fairly conventional, familiar type of city at that.

Copy and paste the snippet above into this text box, but change the highlighted elements to either something conventional and familiar, or something really science-fantasy.
