Sci-fi readers are wonderful people. There are things they take in stride (so long as they fit the world) that other readers might collide with, bounce, and stare at as they wondered who put the wrong words in the blender. Spaceships unloading into a depot that also has animal-powered transportation? Why not. In many ways, depending on the nature of the world, or the type of colony and culture, high tech for big things and low tech for small things makes perfect sense.
There’s a scene in an episode of Firefly where the main character gets into a bar fight. In classic Western-style bar fight tradition, said character goes out the main glass window. Except . . . the window is a force field that drops, allows our hero to sail through it, and then re-forms. Is it a waste of energy, and possibly the money needed to pay for the energy, to replace a window with a force field? Well, it depends. In the story-world, power generation is really cheap, force fields are cheap, anti-grav hover tech is cheap. Glass is expensive, presumably because the colony worlds don’t have the tech to make large pieces of plate-glass*, so which makes more sense for the bar owner?
In the RajWorld universe, moving mass between star-systems is expensive but moving data is even more expensive. Passengers and cargo can get from Home to Shikhari, Eta Tolima, LimWorld, WemWorld, and other places for less money and faster than a routine government communication broadcast travels. Emergency comms do outpace cargo and passenger vessels, but the cost is staggering. So what gets transported, aside from people? Luxury goods, unusual things and exotic medicines, art, equipment for necessities like city-size force-field generators, the machines to make other machines, and so on.
Those all cost a great deal of money. So why pay for an anti-grav transport for local no-rush bulk goods like grain or food that are just moving a few tens of kilometers when you can hitch up four wombows and go? If you are fishing or boating near-shore or on a lake, why not use sails or an electric outboard motor? Since the Staré are quite willing to work for humans, making labor inexpensive (for some things), food synthesizers, insta-cookers, and other tech doesn’t make sense for people who can hire a Staré to cook, or who buy food from Staré and human take-away shops (which appear like the proverbial mushrooms after rain as soon as someone finishes a new spaceport or cargo distribution center. Staré learn very quickly.) Some people find Staré-made goods to have better quality for the cost when compared to purely machine fabricated things, although the fit is equally good. The micro-level tech (medical, some environmental, weaponry) is very high, the macro-level tech (interstellar transport, protective domes and shields) is very, and the middle ranges from pretty high tech to wombow carts and hand-sewn clothes made from locally synthesized fabric decorated with trim a Staré wove on a back-strap loom.
I suspect, once real-world humans figure out how to escape the Sun’s gravity well and spread beyond our own home system, tech blends will appear on worlds where the environment supports them. Domed cities a la Grayson (Honorverse) and in older stories will certainly be possible, and pure high-tech colonies as well, but moving mass is expensive, and someone, somewhere, will get frustrated when something expensive breaks, will look at the local domesticated livestock that is large enough and docile enough to use for traction, and re-invent the wagon and cart. Never underestimate the creativity of ticked-off individuals. It is rivaled only by that of bored individuals.
*The Union government in Firefly takes the cake in many ways if you are looking for “how not to run my interstellar empire.” There’s a difference between benign neglect and “ignore their pleas for assistance as long as the taxes get paid on time.”
