How are retroviruses depicted in science fiction?

One common scenario is the retrovirus - caused apocalypse. The virus spreads rapidly, wiping out most of the human population, leaving only a few survivors to fend for themselves in a post - apocalyptic world.

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.

Thermodynamics in science fiction can be seen in concepts like time travel. Some theories suggest that time travel might violate the second law of thermodynamics as entropy would seem to decrease in certain time - travel scenarios. In many science fiction movies and books, when advanced civilizations are depicted, they often have mastered thermodynamics to an extreme degree, being able to harness vast amounts of energy with near - perfect efficiency, much like a Carnot engine in an idealized form.

Often, singularity is depicted as a sudden and drastic change. For instance, in many AI - related science fiction, the moment of singularity is shown as a quick leap where machines gain self - awareness and start to improve themselves exponentially. It's like a switch being flipped, and then everything changes very fast.

In science fiction, farmers can be depicted in various ways. Sometimes they are shown as traditional caretakers of the land, but in a futuristic setting. For example, they might use advanced machinery to cultivate genetically modified crops. They could also be part of a post - apocalyptic world, struggling to grow food in harsh conditions.

Often, it's depicted as a revolutionary financial system. It might be shown as a way for characters to quickly and anonymously transfer large sums of money across vast distances, like in a space - faring civilization where different star systems need a seamless way to conduct business.

In science fiction, smartphones are often depicted as highly advanced devices. They might have capabilities like instant holographic communication, being able to access any information in the universe, or even control complex machinery remotely. For example, in some sci - fi stories, a character can use their smartphone - like device to hack into an alien spaceship's security system just by a few taps on the screen.

In science fiction, Chicago is often depicted as a post - apocalyptic landscape. For example, in some stories, the city might be in ruins after a major disaster like a nuclear war or a massive alien invasion. Buildings are crumbling, and the once - bustling streets are desolate.

Often, spice is depicted as a very valuable and scarce item. In many science fiction settings, it's something that's difficult to obtain. For instance, in certain space - faring stories, it might only be found on a particular planet or in a specific region of space.
