Some 65 million years ago, the dinosaurs vanished from the Earth. There are many hypotheses as to why these great reptiles no longer walk among us. One current of thinking goes thusly: dinosaurs were masters of the Earth for so long that they became complacent. Because their reign was indisputed, they evolved in ways that were not optimized for survival. Thus, the strange crests of the Hadrosaurs. The weird dome head of the Pachycephalosaurs. The giant frills of the Ceratopsians. Like Victorian ladies' hats, the dinosaurs became increasingly baroque until they were too ungainly to survive.
I worry that The Magazine of Fantasy and Science Fiction is heading in that direction. I'm all for literary quality in my sf mags, but F&SF has been tilting so far in the purple direction that it is often all but unreadable. I present Exhibit A: the July 1961 "All-Star" issue.
