The excerpt provided in the question highlights traditionalists' preference for low-tech amenities, as shown through Ting Ting's parents in the text.
The piece of textual evidence that best supports the idea of traditionalists preferring lowTech amenities is:
"They're old models, mid-twenty-second century, that Ting Ting bought at a junk auction last fall and restored by watching instructional videos on the Net. We usually don't take them out. Ting Ting's parents, Ms. Chen and Auntie, are traditionalists and prefer lowTech amenities."
This excerpt clearly shows how Ting Ting's parents, who are traditionalists, opt for older, low-tech options like the old dust bots instead of modern ones.
