Right now there are companies working to grow meat. Not cattle or pigs or other livestock that has to be slaughtered and processed. Just meat. To eat.
There’s laboratories where human meat is being grown, organs, livers and kidneys and hearts, for spare parts to replace ones in people, that are failing.
50 years ago all this was science fiction. What will it be in 50 years from now? The time will arrive when we can grow entire humans from a template. Ever see the movie Blade Runner? Different companies supplied different body parts, brains, eyes and so on, and there was one large corporation that assembled these parts, on order, to make specific types of workers, mostly for either dangerous jobs or as sex workers. Work is going on right now to make this a reality.
At the same time, our ability to make implants that augment human senses is rapidly increasing, and true androids may some day be commonplace, as people augment themselves with night vision, telescopic vision, brain implants, the mind boggles. Mine does anyway.
I can see a future where people are either grown or assembled to do specific jobs. Where astronauts are produced with extreme resistance to radiation and can live for many hundreds of years, enabling them to travel between the stars. That’s assuming we haven’t worked out wormholes or some exotic warp drive by then to zip back and forth between star systems with.
The Elite, the Leaders, may be purposely created with extremely high IQs, or humanity as a whole may be selectively created this way. It’s fun to speculate on what our directions may be, but there’s no speculation necessary to know that we’ll continue to advance technologically.
