My greatest hope for this tech is that it makes beautiful details like you have on 19th century buildings cheaply available
My house (in Europe) was built in 1906. It is pretty ordinary. Perhaps you meant 19th century?
But yes I think 19th century is probably closer to what is meant.
The Bauhaus school was closed in 1933. Brutalism as a movement was popular from the 1950’s to the 1980’s.
The problem is, “beautiful old look” can mean many different things to many people! Also, old buildings have the advantage of survivorship bias—the cheapest/ugliest/least functional buildings usually get demolished.
