There is no such thing as realism in science fiction, most of the sci-fi is fantasy. Some things can be true according to the laws of nature, some are already gone. I am giving my personal opinion about what will come or not.
Mind reading
The mind can be read by analyzing the patterns of the brain. Telepathy is a fake thing, but it is very possible to recover the thought by analyzing the signal read by the instrument. Mind controlled robots, drones are already there, pictures of the mind can be seen a lot. These will come in the market in the future. Dream recorder, player is also possible. Sending data directly to the brain to give feeling, it is very possible to teach something, although what is the feeling goddess, what to teach will have to wait a long time.
Quantum computer
Allready gone, getting stronger day by day. The new algorithm is ready, work in progress. Will come to the market in full force.
Fusion engine:
I am not entirely sure why energy is still not being used in fusion, otherwise a huge source of energy will come into our hands. We can dream of a Proxima Centauri if we can get rid of the nonsense about nuclear reactions in space and get a fusion engine in our hands.
Genetic engineering
With the help of Crisper and other such tools, genetic engineers in the group will be able to tell you what is possible - but in the future there may be a trend to have customized intelligent, strong babies. Efforts have been made for a long time to bring the mammoth back. It may be possible to make dinosaurs by reverse engineering in the future.
Quantum Teleportation:
This thing is called misleading, it is not true teleportation, and information cannot be sent faster than light. Influence is no longer information. I will write details about it one day. It can be used to copy objects with stat - it takes light speed to get the effect, but so what? Ordered from Amazon, the product was immediately copied on the phone type thing - it is theoretically possible.
Smell recorder:
Leaving various molecules in a box and leaving it on time! I hope it will come to the market one day.
Wormhole
Wormholes are unlikely to be created in the lab in the future. I am not optimistic about it.
Time travel in the past
I am not optimistic about this either. If it possibly happen, we could see some visitor from future. But we are not seeing it. Oh! There is another chance that, it can be happening. If they visit, but they, I think they never can talk with us or we can't hear them. They will be invisible.
Cryo slip :.
Putting people to sleep, then waking them up. Wormholes are fairly impossible, I don't see any option to travel the galaxy without cryoslips. Not optimistic about it either.
Head Transplant:
Cut off one's own head and put it on another's body. Possible, tested on animals. However, there are many problems, the receiver becomes paralyzed, the spinal cord cannot be connected. People were supposed to be tested, but they weren't. Will come in the future.
Conscious Robot:
We still don't know what consciousness is, research is going on. Integrated information theory seems promising. Not sure if the Kansas robot will ever come. AI is just a program, not something conscious.
12. Meet intelligent aliens:
Seems almost impossible :( but also there is some possibility to find them. Becouse we don’t know about maximum of the galaxy. They are remain unknown. We are not able to find them right now becouse of the distance. But hopefully future generation could find it.
Write your opinion in the comments about what might be possible.
Thank you.
My bet is still on genetic engineering. It's already in development after all. Same with the quantum computer but in the end, it's still an AI
