"I was disappointed in my profession," says architect Shigeru Ban in today's talk, which he gave at TEDxTokyo in May. As far as he's concerned, architecture has lost its way. "We are working for privileged people, for rich people, for government and developers. They have money and power, and those are invisible, so they hire us to visualize their power and money by making monuments of architecture." Ban, instead, has committed himself to creating buildings that can truly be useful -- whether or not they're permanent fixtures on a horizon.
