On the topic of FLW, I've visited a number of his houses. One of my friends growing up lived in a Wright house. I've visited Wright's personal house, Taliesen. In my opinion, Wright is not really an architect.
I consider Wright more of a sculptor or an artist. His designs are terribly impractical, and are not versatile in the least. Additionally, he didn't account for the limitations of the materials he was using to build his structures. So his buildings tend to require a lot of repairs, and many have structural problems, leaks, as well as general safety issues.
Wright wasn't the least bit apologetic about any of these things, and it seems like Viñoly shares the same overwhelming egotism.
On a somewhat hilarious note, when I went to visit Taliesin, there were several rooms which I thought were poorly designed, but had an element that I considered a saving grace. In literally every single instance, it was something his wife had added/altered after his death.
So, point being, I think that when you allow an egotistical architect to design something without any sort of editorial limitation, you probably end up with a worse product overall.
