Your supposition runs counter to what has been documented many times by many industry publications and general purpose newspapers.

I know about ten very good architects who work on very large projects around the world. Two of whom would deserve to be called "starchitects," if they were interested in self-promotion. Wright is well-known in the professional architecture world as someone whose buildings are great when the go up, but quickly reveal their flaws once lived in and used.

The Imperial Hotel in Japan survived a massive 1923 Tokyo earthquake due to several design decisions made by Wright

One building out of over a thousand. Oak Park, Illinois has no shortage of homes that have become well-publicized money pits because of Mr. Wright's choices.

Heck, his very famous Fallingwater house is considered one of his crowning achievements, but is also a spectacular failure. He built it over a waterfall, and didn't take humidity into consideration. He built it in Pennsylvania and didn't take winter into consideration. Defects in the concrete floor designs were noted even during construction. Nothing to do with age.
