intelligence is being vastly amplified by AI
Ubiquitous, large-scale automation has led
to vast swathes of human employees being replaced by virtual or robotic
counterparts. Strong AI now occupies almost every level of business,
government, the military, manufacturing and service sectors.
than being separate entities, these AI programs are often merged with
human minds, greatly extending the latter's capability. For instance,
knowledge and skills on any subject can now be downloaded and stored
directly within the brain. As well as basic information and data,
this includes physical abilities. A person can learn self-defence,
for example, become an expert in any sport, or be taught to operate
a new vehicle, all within a matter of seconds.

– something which a significant minority of the population still refuses
to accept. Compared to transhumans, these non-upgraded humans are becoming

floating cities are roaming the oceans
At the dawn of the 22nd century, many of the world's cities lie partially submerged due to rising sea levels.* Despite some attempts to build flood defences, even famous locations – such as New York, London, Hong Kong, Shanghai and Sydney – have been affected. With over 10% of the world's population living on coastlines, hundreds of millions have been forced to migrate.
While many citizens have abandoned their homelands, a growing number have adopted a new means of living which does away with national boundaries altogether. This comes in the form of floating, artificial islands – entirely self-sufficient and able to cruise around the world indefinitely.*
These ships provide comfort, safety and security, in stark contrast to the upheaval and chaos experienced by many land dwellers. In addition to a continuous supply of food and freshwater, various facilities are available including virtual reality suites, state-of-the-art android servants/companions, swimming pools, landing pads for anti-grav vehicles and much more. Carefully maintained arboretums with real trees can also be found on board (flora which is becoming increasingly rare these days).
These giant, amphibious ships are especially popular in Southeast Asia, which has been hit hard by the effects of climate change. Some of the largest craft house upwards of 100,000+ residents. Whole new cultures are forming on these "micro nations" – often based around particular themes, lifestyles, ethics or belief systems that appeal to a specific demographic.
Seasteading in general has exploded in recent decades. In addition to city ships, permanent settlements have appeared along the flooded coasts of many regions. This often takes the form of recovered infrastructure rebuilt to accommodate rising sea levels. In the more prosperous nations, cities may be rebuilt using massive anchored pontoons or other hydrostatic devices. More commonly, entirely new cities are devised by governments to accommodate the displaced populations of coastal cities.
New, larger and more advanced versions of the Energy Islands built in earlier decades make up the majority of these settlements. Some consist of huge artificial archipelagos, stretching for tens of kilometres. Units are often covered in natural plant life, in addition to hi-tech systems for carbon sequestration.

As well as CO2 capture, offshore settlements play a role in scrubbing general air and water pollution, acting as giant filters that remove trash and chemicals from the ocean. These materials can then be recycled and put to new use. This is now having a significant impact in reversing the enormous damage that has accumulated over the centuries from ocean acidification, plastic debris, nitrogen and other man-made waste products.**
Needless to say, these settlements, both stationary and roaming, are entirely carbon neutral. Power is produced from a combination of OTEC plants, offshore wind farms, tidal and wave plants, solar arrays, and other means. Some even utilise fusion. Food is grown and water desalinated locally. These ocean settlements are themselves among the earliest adopters of the so-called "post-growth economy". This had emerged out of the converged crises of resource depletion and advanced automation that began during the mid-late 21st century, and seeks to minimise the impact of human economic activity on the environment.

Penguins face extinction
centuries, Emperor Penguins were the best-loved and most recognised
symbol of Antarctica. By the middle of this decade, their numbers have
dwindled to almost nothing because of melting sea ice, depletion of
krill and industrial activity.* Small populations continue to exist for several more years, by adapting
their breeding habits, but even they will eventually disappear. Emperor
Penguins aren't the only birds vanishing during this time: thousands
of other species are disappearing too, as ecosystems around the

of Mars is underway
no physical processes have been introduced yet, the first serious plans
are being drawn up for the planet's gradual transformation, with the
ultimate goal of making it habitable for humans. Exactly who will be
given control of Mars and its resources – or if the planet should have
complete independence – is the subject of much debate and speculation
around this time.
fields are in military use
combination of several unique technologies, stacked together in layers, has led to a radical new form of protective shielding.* To observers from the previous century, this would resemble the "force
fields" depicted in science fiction movies. When activated, it
provides an instant, near-impenetrable field withstanding hits from
all but the most powerful weaponry.
layer consists of a supercharged plasma window, shaped into a dome or
sphere by electromagnetic fields. This is hot enough to vaporize most
layer underneath contains millions of curved laser beams, producing
a high-energy web that captures projectiles fast or powerful enough
to bypass the plasma window.
layer consists of a "lattice" made from trillions of carbon
nanotubes. These microscopic structures are woven together in an instant,
forming a diamond-hard shell repelling objects missed by the other two
layers. If necessary, this can be extended to cover a larger perimeter,
at the cost of decreased strength. Conversely, it can be reduced in
size to provide an even denser and more durable barrier.
described above can protect against the majority of bullets, bombs and
projectiles. However, they are almost useless against lasers. A fourth
and final layer takes care of this problem. This uses photochromatic particles,
which change their properties when exposed to laser light, effectively
neutralising most directed-energy weapons. An early form of this technology
was seen a century previously, with sunglasses that changed colour when
exposed to sunlight.
to warzones, these multilayered force fields are used in
a range of other situations. National borders, for example, are being made more
secure – as are many sources of food and water production. Corporate
spaces and luxury dwellings owned by the rich are also utilising them.
A number of satellites are being fitted with this technology too.
Large-scale arcologies are emerging as an alternative to traditional cities
The global convergence of environmental issues and resource depletion has forced humanity to drastically readdress the way urban areas are designed. The refugee crisis that emerged in the mid-21st century has now largely subsided, with much of civilization having been relocated to the polar regions of Northern Europe, Russia, Canada and Western Antarctica. In order to accommodate so many people in such a smaller area, cities have become increasingly dense and self-contained.
However, decades of concerted geoengineering efforts have led to success in stabilising global temperatures. Combined with ongoing population pressures, this has prompted governments to begin repopulating some of the abandoned regions in more central latitudes. Despite this progress, most countries still face the problems of resettling hyper-arid, ecologically-ravaged environments. As such, long-hypothesised "arcologies" have begun to emerge as a radical departure from traditional urbanism, condensing an entire city into one massive structure.*
A precedent for these mega-structures could be seen as far back as the 2020s, with construction of the first centrally-planned, truly sustainable cities.** Later in the 21st century, these principles were adapted for the development of single structures – resulting in supertall skyscrapers that combined vertical farming with residential and commercial space, recycling and production systems for energy, water and other resources.*
By the 22nd century, these towers have evolved into some of the mightiest structures ever built: of such immense volume that some cover several kilometres in girth, typically rise over 1.5 kilometres in height* and accommodate millions of people.** Some are partially or fully merged into mountainsides and other landscapes – resembling enormous ant colonies, and living up to their portmanteau of "architecture" and "ecology". This scale of engineering has been made possible through advances in materials science, with carbon nanotubes utilised to cope with the massive forces involved. The sheer size and strength of arcologies makes them virtually immune to earthquakes, hurricanes and other disasters.
Each of these self-contained structures holds everything it needs for human survival. Automation is ubiquitous with intelligent robots managing almost all construction and maintenance.* Highly efficient transport systems are located throughout to move travellers horizontally, vertically or diagonally. Advancements in elevator technology have made lifts capable of whisking riders up in a single trip – no matter what height – as opposed to changing halfway up.* This has been accomplished through improved cable design and, more recently, the use of electromagnetic propulsion.* This kind of hyper-dense urban environment allows movement around a city at speeds unheard of in previous centuries.
These radical new designs exemplify an overall trend in recent human development: low environmental impact. Globally, cities and their connecting infrastructure are slowly being retracted, giving over more land to nature. Advances in transportation and civil engineering, combined with nano-scale manufacturing, are enabling humans to operate with little or no impact on the environment. Though classically designed cities still exist, the arcology represents a fundamental shift in the balance between humans and nature.

at this scale involves working directly with the finest known structures
of matter – such as quarks and strings – to manipulate the properties
of atoms. This development is a further step towards macro-scale teleportation,
i.e. transportation of objects visible to the naked eye. Significant
breakthroughs in anti-gravity and force field generation will also result
area that will see major progress is in materials technology. For example,
metals will be produced which are capable of withstanding truly enormous
pressures and tensile forces. The applications for this will be endless,
but perhaps one of the most exciting areas will be in the exploration
of hostile environments – such as probes capable of travelling within
the Sun itself, and tunnelling machines that can penetrate the Earth's
crust into the layers of magma beneath. Longer term, this development
will pave the way for interstellar ships and the massive forces involved
in lightspeed travel.
exotic materials are becoming possible – including wholly transparent
metals, highly luminous metals, frictionless surfaces, and ultradense
but extremely lightweight structures. As with
many areas of science, femtoengineering is being guided by advanced
AI, which is now trillions of times more powerful than
unaided human intelligence.
control of earthquakes and tsunamis
now, geophysicists have mapped the entirety of the Earth's crust and
its faults, extending some 50 km (30 mi) below the surface. Computer
simulations can forecast exactly when and where an earthquake will occur
and its precise magnitude. With a "scheduling" system now
in place, comprehensive preventative measures can be taken against these
people know when to stay out of the weakest buildings, away from the
bridges most likely to collapse and otherwise away from anything that
might harm them. Rescue and repair workers can be on duty, with vacations
cancelled and extra workers brought in from other areas. Workers can
be geared up with extra equipment ordered in advance to fix key structures
that may fail in an earthquake. Freeways can be emptied. Dangerous chemical
freight can be prevented from passing through populated areas during
the quake. Aircraft can be stopped from approaching a potentially damaged
runway. Weak water reservoirs can have their water levels lowered in
advance. Tourists can be made to stay away. All of these measures can
substantially reduce casualties and economic disruption.
some nations are going one step further and creating additional systems,
in the form of gigantic engineering projects. To protect the most earthquake-prone
regions, a network of "lubrication wells" is being established.
These man-made channels penetrate deep underground, to the very edge
of the mantle. They work by injecting nanotechnology-based fluid or
gel into fault lines, making it easier for rock layers to slide past
each other. Explosive charges can also be dropped at strategic points,
in zones where the lubrication might be less effective. Instead of sudden,
huge earthquakes, the network induces a series of much smaller earthquakes.
Using this method, an earthquake of magnitude 8.0 can be buffered down
to magnitude 4.0 or lower, causing little or no damage to structures
on the surface. In coastal locations, tsunamis can also be prevented.

by no means perfect. There are complex legal and liability issues in

uploading enters mainstream society
Adequate hardware to support human-level intelligence was available
as far back as the 2020s, thanks to the exponential progress of Moore's
Law.* This made it possible to form
simulations of neural processes.*

proved to be a vastly greater challenge. Full transfer of human consciousness
into artificial substrates posed enormous technical difficulties, in
addition to raising ethical and philosophical issues.

many legislative barriers that stood in the way – meant that it was

of memories and thought patterns, allowing some limited experience of
the mind uploading process. However, it was only through the emergence
of picotechnology and strong AI that sufficiently detailed scanning
methods became available. This new generation of machines, being orders
of magnitude faster and more robust, finally bridged the gap between
organic human brains and their synthetic equivalents.
tested on monkeys, the procedure was eventually offered to certain marginalised
people including death row inmates and terminally ill patients. Once
it could be demonstrated as being safe and reversible, the project garnered
a steady stream of free and healthy volunteers, tempted by this new
form of computerised immortality.

ever enacted into law. Religious and conservative groups voiced their
objections to what they saw as a fundamental violation of God's will.
At times, this threatened to postpone the technology indefinitely. Eventually

on. The level of demand for mind uploading proved to be enormous, and
the treatment was made commercially available in the 2120s.
citizens have access to special clinics in which their biological brains
can be literally discarded in favour of artificial ones. Rather than
simply "duplicating" a mind, the machine physically shifts

replaced – piece by piece – so the original personality remains intact
during the transition. This vital aspect of the procedure assuages the
fear which many have of losing their identity.

"Perfect" simulations of one cubic metre
In the early 21st century, supercomputers used a simulation technique called lattice quantum chromodynamics, performing calculations by essentially dividing space-time into a four-dimensional grid. With a resolution based on the fundamental physical laws, they could simulate only a tiny portion of the universe accurately – on the scale of one 100-trillionth of a metre, slightly larger than the nucleus of an atom.*
At best, algorithms were able to demonstrate the strong nuclear force among protons and neutrons and its effect on nuclei and their interactions. This was achieved in femto-sized universes where the space-time continuum was replaced by a lattice, with spatial and temporal sizes on the order of several femto-metres or fermis and whose lattice spacings (pixelations) were fractions of fermis. Lattice gauge theory revealed new insights into the nature of matter, but was still fairly limited in scope.
However, computer power and information technology in general were growing exponentially. In fact, they had followed a remarkably smooth and predictable trend throughout the 20th century.* This growth rate continued its consistent path in the 21st and 22nd centuries.*
By 2140, a region of space measuring 1 cubic metre can be simulated in near-perfect detail, down to the smallest quantum unit.* This landmark in physics has profound applications. It soon paves the way for larger simulations of two metres, providing absolutely accurate representations of the entire human body. Scientific experiments on these and similar-sized objects can now be literally as controlled as they can be – with data obtained far more reliably and much faster than in real-world and real-time settings.
Holodeck-style environments become possible in the latter half of this century, as these simulations continue to increase in detail and spatial extent, reaching tens of metres and greater. This offers a level of realism that was unavailable with full-immersion virtual reality. To an observer placed in these miniature universes, it would be almost impossible to distinguish reality from fantasy.
