With all due respect, it doesn't sound reasonable to me.
In fact it seems to be a serious 'failure of imagination' on the part of 'SF writers' (I would probably dispute that title) and Hollyweird.

Failure of imagination for hollyweird is the default setting...nothing new there.
(full disclosure...I've been reading science fiction since the early sixties...I've read several thousand books...I've even written a few myself)
