The issue is not due to build time, it's related to choice of materials used. The glass doesn't necessarily fail, its performance goes down due to loss of insulative properties after some time in service. By that time the developer is long gone and unit owners are left with skyrocketing maintenance fees due to heating and maintenance of the old leaky glass.

I has John Straube (interviewed in that article) as my building science prof while I was in uni, he's quite knowledgeable and has done extensive research in this field, so I would trust him when he says many of these buildings will fail after a decade or so in service. I have a unit in a glass building and my maintenance fees have started to go up quite a bit recently. I'm planning to sell it in the near future because of this very issue.
