Chronological snobbery is a whiggish habit.
If anything, architecture today is lazy and mediocre, especially given our technological advantages. People even used to factor in the path of the sun and the direction of the wind to position a house. Some architects and contractors might still do that, but I don't think this is common, because, hey, we have HVAC, and hey, we just want to slap together and flip a shitty development as quickly as possible.
The lack of care, the lack of concern for urban planning, the misuse of material in a given environment, the use of inferior materials and building methods, the lack of concern for posterity who will inherit our mess, the waste, the ugliness -- it's all shameful. If anything comes out of this "green revolution", I hope it is at least a course correction in this space.
