The prediction of the future is always risky. Even the prophets of the Bible did not speak far ahead, but judged the realities they saw and predicted the future precisely because of their discernment. There are 25 years left until 2040.
Undoubtedly - technical progress (provided that we do not destroy, there will be no crazy and warlike neighbors left).
The most important thing is the relationship between people. I don't dream of communicating with thoughts or thanks to implanted devices. I hope that in 25 years, people will remain, or perhaps become, empathetic to those around them and to the environment - living and non-living nature. They will stop devastating nature, wisely manage and use resources, perhaps they will control the unbridled desire for wealth and power, and democracy will take more sustainable and humane forms. And I'm hoping for smarter rather than dumber fellow citizens who won't run to hide when they see a flying passenger plane that leaves a "tail" of smoke and doesn't burn 5G towers...
I hope for a reasonable breakthrough in the preservation and maintenance of health, keeping the criterion of reasonableness and not resorting to experiments that go beyond the limits of humanity and reason. Nature (or perhaps the Creator) draws new surprises in all areas. With the advancement of medicine, bigger and more complex challenges and ugly diseases appear (or are discovered).
I said it! It's expropriating.
