Architecture schools don't really teach you the pragmatic side of the trade. Their projects are building those sorts of abstracted models, talking about forms and voids. It is just so far abstracted from the sort of practical architecture that leads to stuff like built in cupboards in a Sears catalog home. Something to also consider is while these young architects are getting trained they aren't really living like adults either. They are in their early 20s after all, still perhaps lashing out in reflexive opposition from their suburban upbringing, and probably don't understand why a built in cupboard would be so exciting.

The results will absolutely be the same. Having spent the first 12 years of my life in a commie block apartment, the absolute best thing that has happened to that building over the years is the trees have covered progressively more of the ugliness. Note that this article is about external visuals, not the layout or any other consideration relevant to buildings being "designed for people to live in". This is about buildings being designed for people to look at.

You can design two buildings for people to live in, make them identical in layout and build quality but one of them has slightly more classical style of architecture and people will invariably prefer it, all else being equal.
