In a sci - fi novel, the most developed world might have advanced technology like instant teleportation. This would allow people to travel across vast distances in an instant, eliminating the concept of long - distance commuting. Also, there could be artificial intelligence so sophisticated that it runs all aspects of daily life, from managing resources to providing personalized education for every citizen.
Typically, the most developed world in a sci - fi novel has highly advanced medical technology. Diseases that are incurable today, like certain types of cancer or genetic disorders, would be easily treated or even eradicated. They may also have mastered space travel to a great extent, with colonies on other planets and regular interstellar trade. Their energy sources are likely to be clean and unlimited, such as harnessing energy from black holes or some other yet - to - be - discovered source.
Well, in a scifi novel, the most developed world would probably have buildings that can change their shape and function according to the needs of the inhabitants. The society might be post - scarcity, meaning that basic resources like food, water, and shelter are so abundant that no one has to worry about them. Their communication would be seamless, perhaps through direct neural links, enabling people to share thoughts and information without the need for spoken or written language.
