How is this day in the future depicted in science fiction?

Science fiction depicts future armies in diverse ways. There are those that are almost entirely mechanized, with soldiers operating giant mechs. These mechs can have a variety of weapons and capabilities. Another common depiction is of future armies that have mastered time - space manipulation, allowing them to travel instantaneously or create strategic advantages. The appearance of the soldiers can range from human - like but with enhanced features to completely alien in form, depending on the setting of the science fiction story.

They can shape the future worlds in many ways. For instance, they might control the distribution of resources. If a corporation has a monopoly on a crucial resource like energy or water, it can greatly influence how people live. They can also determine the level of technological progress. If a corporation decides to halt the development of certain technologies for its own profit, it can slow down the overall progress of the future world.

Another scenario could be a world where digital identities are completely managed by blockchain. Every person's identity is stored in a secure and decentralized way. This would enhance privacy and security, as no single entity could easily manipulate or steal identities. Also, in the realm of supply chain, blockchain science fiction often depicts a seamless and transparent supply chain system. Every step of a product's journey, from production to delivery, is recorded on the blockchain. This helps in reducing fraud, ensuring product authenticity, and improving overall efficiency.

In science fiction, climate science is often depicted in extreme ways. For example, in some stories, global warming has led to the complete submergence of coastal cities. This shows the potential consequences of our current disregard for the environment.

In science fiction, reproductive science can be depicted in various ways. For example, in some stories, there might be artificial wombs that allow for gestation outside the human body. This concept challenges our traditional view of reproduction. Another way could be genetic manipulation for creating 'designer babies' with enhanced abilities or specific traits, which raises ethical questions about playing with the building blocks of life.

In science fiction, ecology can be depicted in various ways. For example, some works might show a post - apocalyptic world where the ecology has been severely damaged due to human mismanagement or a cataclysmic event. Others may present alien ecologies that function very differently from Earth's, with unique organisms and ecosystems. Some science fiction also explores the idea of terraforming, which involves modifying a planet's ecology to make it more habitable for humans.

In science fiction, communism is often depicted as a utopian social system. For example, in some works, there is no class division, and resources are equally distributed among all people. Everyone has access to quality education, healthcare, and housing without the constraints of capitalism like profit - seeking and exploitation.

Altair in science fiction can be presented as a place of great mystery. Writers sometimes use it as a destination for space exploration. Spaceships in these stories journey towards Altair, facing various challenges like interstellar radiation and asteroid fields along the way. It's often a symbol of the unknown and the vastness of the universe.

In science fiction, angels can be depicted in various ways. Sometimes they are presented as highly advanced alien beings with angel - like appearances and extraordinary powers. For example, they might have wings that are not just for show but are some kind of advanced biological or technological appendage that allows them to fly in different gravitational fields or even travel through dimensions.

In science fiction, infertility can be depicted in various ways. Sometimes it's a result of environmental disasters. For example, in some post - apocalyptic stories, the polluted environment has made it difficult for humans to reproduce. It could also be a side - effect of some advanced scientific experiments gone wrong, where genetic manipulation has led to infertility in certain populations.
