Left-of-center, but not left behind in transhumanism

I was scared for a few hours when KurzweilAI.net posted the trailer for a film adaptation of Ayn Rand's Atlas Shrugged last week, along with what looked like an unedited press release and no critical reaction.

What did Ayn Rand have to do with transhumanism? If transhumanism wasn't exclusively libertarian, why promote an author better known for libertarianism than anything? Why risk alienating the Left unnecessarily?

I'd recently read, in Cory Doctorow's review of a book, that transhumanism had originated among libertarians, that it had faced plenty of criticism from liberals, and that the book's effort to reconcile it with democratic socialism was long overdue. Was this pessimistic picture accurate? Would being a democratic socialist alienate me from transhumanism and vice-versa?
