Modernism

I've always wanted a sleek, modern home and will someday build one like this (which was built for only $200k). When I told a friend recently, he kind of recoiled at the thought of a cold boxy object, and I shared a quote I heard recently that went something like this:

We live in the 21st century in America, but people still build and choose to live in homes that look like they are 150 years old. Why is that? Why shouldn't new homes look new?
