What part do you see being a reality in 29 years?
They can use their connector on their hair in the movie, to connect with animals, plants, and other people around them. I think a form of that is happening right now, and at the rate technology is increasing there will be big advances. They put nuero link in monkies, and had them playing video games. How much it helped in that i don't know. Human trials should start this year. There will be a way for humans to connect to their environment and a possibility of an in body connection to the mind of animals or other people in the future. It would most likely be (human mind to computer- computer to other human/animal-and back to the computer) cycle. There are already implantable chips that connect with cars, computers, locks, etc
They have been 3d printing parts of the body for awhile, and are growing chimera organs in animals for human use. Growing a biological body is not out of the question in the next 20 years, it might be more mechanical than bilogical, (as the current outlook) and maybe being able to do a brain transplants. Robotic bodies and ai minds are getting pretty advanced.
If they collect enough data on people, they can create holograms that would be hard to distinguish a conversation with the actual person. Sometime in the future if someone were talking with the avatar of someone in something like the metaverse, you would have a hard time telling if it is the real person or an AI driven avatar
