What sci-fi prediction are you very confident about in the next 50 years?

That is, if you brought up the idea today, people would say it's sci-fi, but you have high confidence it will become a reality.

@urusan The human races' existence depends on large pharmaceutical companies because:
1. woman and mankind are so divided that the general public resorts to fertility or artificial womb services; thus, every newborn is vulnerable to nonconsentual genetic modification
2. it is fashionable to elect for body modifications that require maintenance or subscription medicine
3. the human immune system has been rendered obsolete or nonfunctional

@likho
1. is described in detail on Huxley's Brave New World.
2. is quite usual on several sci-fi books and movies - an extension of today's aesthetic surgery.
3. is the real novelty - and a very plausible one now.

@manuelcaeiro @likho Well, my question about how #3 would work is more technical. How would we keep people without working immune systems alive?

Shutting them down is relatively easy and some forms are possible today: a bioengineered HIV-like retrovirus, regular doses of immune suppression drugs, or (epi)genetic engineering.

However, keeping the immunocompromised population alive is much harder. Even in cases today, we have to keep the immune system going.

@manuelcaeiro @likho While it's definitely theoretically possible to replace the immune system, it seems like a monumental technical challenge. The kind of thing that could take much more than just 50 years, and has a low certainty of success in the near future.

That said, I could imagine a situation where immune suppression is normal, and pretty much everyone is immunocompromised by today's standards, even though their immune systems are still functioning.
