There are two general requirements - power and space. Power 1,000,000 humans need about 2,000 calories per day each plus energy for day-to-day functions. Total up the calories and convert it to something workable, and we have a total of 96.85 MW. That is a lot, but that pales in comparison to energy. The average US household uses 900 kWH per month, giving ...

For the sake of convenience let’s start with the assumption that your population will desire a North American urban population density and a globally averaged diet. The city of Austin TX has approximately 1,000,000 residents and a surface area of approx. 800 km^2, for a density of about 1,250/km^2. The City of New York (5 boroughs) NY also has a surface ...

Your question seems to me to be en reality two questions: 1- why anyone would want to capture a city 2- why just not nuke it, assault it and going forward. First cities are often node in central communication networks, railway and large road go through cities. Those communications assets are very important for an army in order to maintain logistic supply....

Sieges exist in modern times because while there is no fortress wall that the attackers can't get past defending infantry shooting from ambush in a city is extremely deadly to the attackers. Taking a city by force of arms is a bloodbath that will cause big troubles back home for the invader. That leaves either flattening it from the air (bombs or artillery)...

Technically, the fight with the Taliban, Al-Qaeda, ISIS, and other terrorist groups have included several sieges, if the whole wars aren't sieges in themselves. When Osama bin Ladin was hiding in caves, Allied forces were in siege mode. They tried to prevent supplies from entering the underground tunnels, prevented reinforcements from entering & exiting,...

By using the loose definition: siege - cutting off an enemy's supplies and lines of communication. Then a siege makes military sense at all times, periods and epochs. Once your enemy is not fully self-sufficient, you gain from cutting him off. A siege will look different at various times. A siege will also vary in scale, depending on the period.

Sieges make sense when: The location is a MacGuffin, so bypassing it is useless or impossible, or Some person(s) in the location need to be captured alive, or Some thing(s) in the location need to be captured intact and It is possible to both hide deep enough to survive artillery or bombardment, but get back from shelters to fighting positions fast enough ...

The harsh reality is that in our world it's probably not going to be a reality. Not for the masses anyway. Long-lasting cybernetics will most likely be prohibitively expensive and only the very very wealthy will be able to afford them. So we're just going to have to change the world. First, let's produce some really simple large scale production of ...

Allowing for the fact that implanting of cybernetic brain enhancing systems is already happening in certain labs, the product life cycle is not as large of a concern as the product security in my opinion. What happens when 50% of the worlds population is feed artificial memories by an AI system at the behest of communist China for example, or someone pushes ...

What if your implants adapt to you over time? You grow into them, both figuratively and literally. They start off generic with baseline functionality, but over time adapt to your way of walking, moving, idiosyncrasies in your vascular or nervous systems, depending on the implant. Replacing an implant with a new "blank" one might gain you a few new features ...

Presuming the attacking force has modern warfare of even today, a siege requires that there be some reason the attackers don't want to just obliterate the defenders. Or that they are having a hard time doing that. If the attackers simply want to wipe out the defenders they can do this in short order. They can drop a huge variety of chemical explosives from ...

Cochlear implants (CIs) are a lot like a neural implant and auditory brainstem impants (ABIs) are most definitely a neural implant. CIs have been around 50+ years and the implants electrodes are designed to last a lifetime. There have been significant enhancements to the electrode design over that time, but generally patients do not receive upgrades to the ...

In principle, a siege is a strategy with the express goal of defeating your opponent through slowly attritting their forces. With modern warfare’s application of combined arms — the tactical use of land, air, and naval units simultaneously to achieve a tactical goal — the pace of conflict is so fast that battles are either decisive and fast or forces keep ...

It may not be a part of your personal cyberpunk vision, but in a high-tech fictional universe, you could justifiably have self-repairing (and maybe even self-upgrading) components based on nanorobotics technology. Specifically, the nanobots in your world could be injected in the cyborg's bloodstream and be used to "smartly" patch up damaged or faulty parts ...

Judging from recent history sieging is a problem. Yugoslavian war had almost 4 years long siege of Sarajevo. Siege for Aleppo in Syria took time between 2011 and 2016 and although government stated that they control whole city there are still some fights on the outskirts. Main problem with sieging is that you might want something from that particular ...

Siege is still an element of modern warfare. If a faction wants to get in a city and another one doesn't want to let them in, a siege is the natural consequence. We have had some famous examples in the recent years, just to cite a couple: The battle of Stalingrad The Battle of Stalingrad (23 August 1942 – 2 February 1943) was the largest confrontation ...

The most important part of the implant would be the socket; the actual body-machine interface. Fortunately the technology for connectors lasts longer (think of audio connectors and USB).

When you have implants that may take over some of the necessary functions of life, which are implanted not out of medical necessity but for cosmetic purposes, the answer will depend upon one primary factor, and possibly a number of secondary factors. The primary factor is going to be the regulatory environment. It is one thing if a life-saving implant ...

Replacing them is (literally) a pain. In real life, you could classify most prosthetics into two types - ones that go inside you (pacemaker, VP shunt), and ones you wear like clothing (hand, foot). In a cyberpunk setting you often also have fictional ones that are partly inside the body, partly outside, and firmly attached to the skin somehow (ouch?) and ...

The corporations can rent/lease the augmentations instead of selling, so they can keep milking their customers, have a more stable cash flow when compared to yearly new models, and have incentives to think about durability because the parts aren't owned by the consumer but by the corporation. They can rent a turboarm v3.0 to first world customers for a few ...

In your world, prosthetics last forever. https://en.wikipedia.org/wiki/Iron_hand_(prosthesis)#/media/File:Eiserne_Hand_Glasnegativ_6_cropped.jpg You are right about technological innovations, profit motive and the like as regards tech in todays world. And you are writing a fiction which you want to be interesting. Different is interesting. I propose ...

The closest thing I can imagine which is related to cybernetic implant is a pacemaker. How long do they last? Pacemakers usually last four to eight years. Biventricular pacemakers that are combined with an implantable cardioverter defibrillator (ICD) do not tend to last as long -- about two to four years. The lifespan of the pacemaker depends on how ...

Following the theoretical technological roadmap given in Kurzweil’s ‘The Singularity is Near’, you are not far off from transcending biology entirely, assuming that parallel technology has developed that can reproduce and then exceed the computational power of the human brain.

"Ship of Theseus" brain replacement (The details are here). If you have nanotechnology and picotechnology, you can work at a scale below glial cells and neurons. This allows to record and "decode" the operation of every single neuron, one a a time. Each new "nanoneuron" would interface with either existing biological neurons or other nanoneurons. A single ...

Task Specific Incarnations As @WorldPeace suggests, brain replacement is the ultimate physical upgrade; allowing the consciousness to move from body to body and through the discipline of keeping backups and regular body maintenance, escaping death entirely. Once that is achieved, although it will still be nice to have nanites onboard for impromptu repairs, ...

Picotech and Femtotech If you define the technologies available by the scale of engineering that is being supported, then of course the next stage involves Picotech: technology or set of technologies that rearranges matter on the picoscale with something analogous to nanotechnology's scope and precision. It would supposedly allow not only precision ...

That’s a tough question... especially because some of them are questioning the human nature at its core. But as can be seen ..the human strives for any enhancement possible to perfect itself. At some point it might be possible to replicate our brain to such a degree that existence itself becomes a question mark if it really is just like a picture but just ...
