I think that men in particular have for s long time been interested in ideas around living forever, creating 'life', creating things that are 'in their own image'.
Frankenstein is about this I think?
All the sci fi where babies are grown in ways that don't involve women.
And the real life efforts to find a way to do this.
I watched a aliens film recently, one of the new ones, and creating life was key to the story.
I'm sure there's loads more examples.
There's also often a side helping of misogyny in things that reference this.
In sci fi stories loads of the time.
If it's a dystopian story, the women are usually prostitutes. Or eg the new mad Max, imprisoned and used to breed.
In utopian ones women tend to be sexually forward, happy to have lots of casual sexual encounters, that sort of thing.
Female sex slaves come up often.
When it comes to building robots etc.
Along with military uses, and replacing people in manufacturing. That sort of thing. Making a life-like sex robot always seems to be something that's worked on and something of great interest to men. (More tv and news about them then other robots!).
The transhuman stuff also seems to be a particularly male thing from what I've seen.
In the end most of it shows the resentment that men have that they need us because we are the ones who can make babies. This has been true for an awful awful long time.
The sex stuff comes from a similar place- resentment that we can say no. That even if we can't say no we are still not 100% compliant, we don't behave as they want etc.
That's my view s bit out there but it's what I think!
Maybe that's going to called a conspiracy theory now as well!
