In the sci-fi series "Stargate" there are many examples of humanoid alien civilizations which both have ridiculously advanced technology and millennia-old traditions authentically preserved in their cultures and day to day life.
For example, one civilization in the series, the Tok'ra, have faster-than-light travel, advanced computers, energy weapons, and advanced healing devices. Socially they have an advanced legal system and civil rights even surpassing early 21st century humanity, but still prefer to live in dwellings reminiscent of Imperial Rome and High Medieval Europe, with flaming torches giving illumination, walls made of stone, and people wearing robes instead of shirts and pants, or elastic onesies.
At the beginning of the Stargate movie "Continuum" for example, we can see a Tok'ra execution. It is very ceremonial with hooded priests listing the crimes of the convict with Orthodox Christian-style chants in a vaulted underground chamber, while torches and oil lamps provide illumination, and the ceremony lasts at least 3 hours.
In OTL, similar examples seem to only come from traditional Christian churches, mostly Orthodox, but in some cases, Catholic. For example, I've read that in some Orthodox congregations, illuminating the church with electrical lights rather than candles continues to be frowned upon, most prominiently Ukrainian Orthodox churches prefer to adhere to fire-based lighting and the believers attending in traditional robe-like clothes, rather than either Western-style formal suits, or casual everyday clothes.
Would it be plausible to have this traditionalism be extended to other aspects of daily life, not just religious traditions in the 21st century?
