A while ago, Spacekitty asked me (via PM) to post my personal timeline of the future. Rather than post the whole thing at once, I'll post it bit by bit. Just note that it's more concerned with being interesting than being completely accurate. It's possible that many of the things below will happen, but they may not happen in the same way. So basically, this is more literary that scientific. It's also got a different style/type of content than the timeline we all know and love. With that out of the way, here goes:
2020 to 2069
2020s...By 2020, numerous inventions of earlier decades, such as the internet, smartphones, drones, and other robots have become ubiquitous across the world and many programmers work to build ever-more-powerful computers and AI. A boom in electronics manufacturing that started in the previous decade results in intensive mining in many third-world countries, where the needed metals are common. But these supplies run low by 2024 and ever-more-advanced technology and ever-more-extensive mining is needed to extract them. This angers the people living in the mined regions and they often fight violently against the mining corporations. An emerging severe water shortage worsens the problem and by 2025, skirmishes have broken out in many places. Meanwhile, by 2023, two organizations that formed in the previous decade are forces to be reckoned with on the global stage, having convinced entire nations to align themselves with them. These organizations are called BARIUM and COBRAS. The more liberal BARIUM controls many western nations, while the conservative COBRAS holds most eastern nations. A tense standoff between the two begins in 2026 and World War III breaks out in 2027. COBRAS initially has the upper hand and marches across much of Europe and by 2029, many predict a COBRAS victory within one or two years. But then the tables turn.
2030s...In 2030, BARIUM begins making secret technological advances, creating bioweapons and nanoweapons to devastating affect, turning the tables greatly. They even build several military space stations and bomb COBRAS bases from orbit. COBRAS scrambles to catch up, in the process devastating major BARIUM cities such as Harrisburg. But in the end, COBRAS fails and surrenders in 2035. The few leaders that can be found are arrested and thoughts of the victorious BARIUM turn to rebuilding and technological advances. Manned missions to Mars and several asteroids are done with great sucess and colonies start on the moon. On earth, the Capitol Region (formerly Pennsylvania, USA) is revamped, with Harrisburg being rebuilt as New Harrisburg and the cities Pennsylvania City, the Bariumpolis (capitol of BARIUM) and numerous smaller cities are built from scratch. The infrastructure across the world is also revolutionized at astounding speeds during this time, thanks to the extensive use and other, more unorthodox methods. But this new planetary nation will soon have major problems to deal with.
2040s...This decade gets off to a great start before things become terrible. In 2041, the remains of COBRAS resurface, this time turning to terrorism to fight BARIUM. For years, structures get blown up and synthetic viruses and deadly nanobots are released, killing tens of millions. Major cities are nuked, killing millions more and virtually no one feels safe. This all comes at a time when resources are becoming scarce and global warming is picking up. People leave for the moon and Mars in droves. Progress grinds to a halt as all of BARIUM's power is devoted to fighting this threat. But it will be short-lived.
2050s...In late 2050, the chaos of the 2040s comes to an end due to a radical response from the BARIUM government. The first phase is the creation of the BARIUM Army of Transhumans, or BART for short. These are the most high-tech soldiers ever and have even received upgrades to make them stronger, tougher, more enduring, faster, and even ageless. They are also aided by highly advanced computers and robots. Hundreds of millions of people are drafted into this army, including many thousands in space. In the beginning of 2051, mass surveilance is drastically ramped up. Nanodrones with cameras are released in swarms of trillions, able to view every square millimeter of the planet with astounding detail. Computers scan huge volumes of data and use advanced pattern-recognition techniques to predict every person's every move. Scanners capable of reading thoughts are even introduced in many areas. Also in 2051, the penalties for many crimes are increased greatly. The Office of Watchers is established in 2052 to keep track of all this information. With all of these reforms, the rates of terrorism and other crimes drop to virtually zero and the public begins to feel safe again. After 87 million deaths, the Decade of Terror is over. The work on overhauling the world's infrastructure continues and by the end of the decade, it is nearing completion. Progress in space also continues, with more asteroids and more notably, Jupiter's moon Europa are visited on manned missions. People continue to head to the moon and Mars, but at a slower rate. Nevertheless, by the end of the decade, there are 40,000 people on the moon, 5,000 on Mars, 600 on Ceres,
and 70 on Vesta. Security increases are also seen beyond the earth. BART units are deployed to the moon and Mars (and Ceres to a lesser extent), military space stations are installed, and surveilance increases somewhat. BARIUM is about to enter its first true golden age.
2060s...The 2060s mark the beginning of BARIUM'S first true golden age. By 2060 to 2062, many transhuman upgrades are available to common people and by 2064 to 2065, the infrastructure overhaul is completed. It is now possible to travel by car or maglev from any continent to any other and high-hypersonic aircraft are common. Snythetic humans, first considered in the previous decade, are present by 2063 and soon all new humans will be created this way. Many other scientific advancements are made, including the eradication of many common diseases. Ganymede and Callisto are visited and a manned mission to Saturn is a possibility for the near future. People also continue to migrate into space, as it becomes easier and easier to get there. In 2067, it costs less than $10,000 to get a seat on a spaceship to the moon and in 2069 the first space elevator is built. Crime levels continue to be virtually zero and the mood of the public improves. But probelms are beginning to develop. Global warming is one; average temparatures are nearly 5 degrees Celsius (9 degrees Fahrenheit) higher than they were in the 20th century. Overpopulation is also beginning to be an issue, as the population of earth reaches ten billion. In fact, most of the Capitol Region is becoming a giant megacity. But the golden age will persist for a while longer.
