I also read the comments on youtube and one of them describes the series as a "terribly poor example of architectural information - so many unqualified statements, generalizations and assumptions that are simply incorrect"
From the same user:
"Architects often concentrate more on the look of a building than its eventual use or function" That is a very bold statement..... To say that architects downplay the function of building is a ridiculous thing to say.
"The central problem is that architects don't want change in their buildings, so they make it as difficult as possible." False. Architects are legally responsible to act for the betterment of their client and the general public. Being deliberately 'difficult' would result in an eventual loss of their license.
"Changes and remodeling is bound to be ugly." Give me a break, have you seen the Louvre? Or any other updated building, ever?
