The nanobots digest the marrow to create SmartBlood™, with better oxygen-carrying capacity than true blood, more efficient clotting and near-immunity to dis- ease. The rest migrate to the fast-expanding brain for the BrainPal™ computer nestled deep in the brain, is surrounded by a dense network of antennae that sample the electric field of the brain, interpreting its wishes and responding through outputs integrated into the soldiers’ eyes and ears.

John Scalzi — The Ghost Brigades

If you are a science fiction geek like me and didn’t hear about John Scalzi, well then it means you are not a science fiction geek at all. The Ghost Brigades is a space opera where human race continues its fight against intelligent races in the Milkyway Galaxy.

Everything happens in a distant future of our world where humanity has already advanced through 23 socio-technological shifts. The chapter you are reading above is giving you examples from the last 2 shifts, namely the Designer Beings and Neurotechnologies. Here the human genome of the Colonial Defense Forces are directly and deliberately edited and the soldiers have fully artificial memory implanted in their brain (which is called the BrainPal).

OK it is our future, but how do we get there? In this article I will guide you through the first fundamental advances of our planet (the first 21 shifts) which will help us to rule the Galaxy. Or, let’s say the outer rim of the Galaxy if we wanna do it fully compliant with GDPR! And I will call this journey the Deep Shift, hopefully with the “f” letter until to the end.

First things first, we have some basics already in place which I call the core elements:

1) physical components

2) smart components

3) connectivity components

These core elements are amazingly accessible. For instance, a Raspberry Pi computer costs not more than 35 Euros.

What we do in Datapao is a part of the Deep Shift

These 21 levels have been published by The World Economic Forum in 2015 after surveying 800 global executives which I found in the book, The Fourth Industrial Revolution by Kalus Schwab. I am writing this in 2018. So I will be updating a few of them already.

Industry 4.0 focuses on Cyber-Physical Systems (CPS), intelligent production, humancomputer interaction, 3D printing, remote operations, Internet of Things, cloud computing, big data and other modern technologies. You will see that these are somehow related to all these “shifts” mentioned below.

Shift 1: Implantable Technologies:

The tipping point: The first implantable mobile phone available commercially

By 2025: 82% of respondents expected this tipping point will have occurred

The people are becoming more and more connected to the devices. Smart tattoos, smart dust, unique chips, and implanted devices will likely also to communicate thoughts normally expressed verbally through a built-in smartphone. With smart dust, doctors will be able to act inside your body without opening you up, and information could be stored inside you, deeply encrypted, until you unlock it from your very personal nano-network

Shift 6: A Supercomputer in Your Pocket

The tipping point: 90% of the population using smartphones

By 2025: 81% of respondents expected this tipping point will have occurred

By 2019 we are reaching to 60% already and GSMA forecasts that Africa will have over half a billion smartphone users by 2020.

Shift 7: Storage for All

The tipping point: 90% of people having unlimited and free (advertising-supported) storage

By 2025: 91% of respondents expected this tipping point to have occurred

A clear trend of commoditizing storage capacity exists. One reason for it is that the storage price has dropped exponentially (by a factor of approximately ten, every five years). An estimated 90% of the world’s data has been created in the past two years, and the amount of information created by businesses is doubling every 1.2 years

Positive impacts

– Legal systems

– History scholarship/academia

– Efficiency in business operations

– Extension of personal memory limitations

Negative impact

– Privacy surveillance

Unknown, or cuts both ways

Shift 8: The Internet of and for Things

The tipping point: 1 trillion sensors connected to the internet

By 2025: 89% of respondents expected this tipping point to have occurred

With continuously increasing computing power and falling hardware prices, it is economically feasible to connect literally anything to the internet. Intelligent sensors are already available at very competitive prices. All things will be smart and connected to the internet, enabling greater communication and new data-driven services based on increased analytics capabilities.

Experts suggest that, in the future, every (physical) product could be connected to ubiquitous communication infrastructure, and sensors everywhere will allow people to fully perceive their environment. For example, The Ford GT has sensors and 10 million lines of computer code in it.

More than 50 billion devices are expected to be connected to the internet by 2020. Even the Milky Way, the earth’s galaxy, contains only around 200 billion suns!

Shift 13: Artificial Intelligence and Decision-Making

The tipping point: The first Artificial Intelligence (AI) machine on a corporate board of directors

By 2025: 45% of respondents expected this tipping point to have occurred

Here the survey respondents are giving a score 45% which can be a bit more biased than the others. Because they are the members of those boards.

Beyond driving cars, AI can learn from previous situations to provide input and automate complex future decision processes, making it easier and faster to arrive at concrete conclusions based on data and past experiences.

Positive impacts

– Rational, data-driven decisions; less bias

– Removal of “irrational exuberance”

– Reorganization of outdated bureaucracies

– Job gains and innovation

– Energy independence

– Advances in medical science, disease eradication

Negative impacts

– Accountability (who is responsible, fiduciary rights, legal)

– Job losses

– Hacking/cybercrime

– Liability and accountability, governance

– Becoming incomprehensible

– Increased inequality

– “Falling foul of the algorithm”

– An existential threat to humanity

Shift 14: AI and White-Collar Jobs

The tipping point: 30% of corporate audits performed by AI

By 2025: 75% of respondents expected this tipping point to have occurred

AI is good at matching patterns and automating processes, which makes the technology amenable to

many functions in large organizations. An environment can be envisioned in the future where AI

replaces a range of functions performed today by people.

Positive impacts

– Cost reductions

– Efficiency gains

– Unlocking innovation, opportunities for small business, start-ups (smaller barriers to entry, “software

as a service” for everything)

Negative impacts

– Job losses

– Accountability and liability

– Change to legal, financial disclosure, risk

– Job automation (refer to the Oxford Martin study)

Shift 15: Robotics and Services

The tipping point: The first robotic pharmacist in the US

By 2025: 86% of respondents expected this tipping point to have occurred

Robotics is beginning to influence many jobs, from manufacturing to agriculture, and retail to services.

According to the International Federation of Robotics, the world now includes 1.1 million working

robots, and machines account for 80% of the work in manufacturing a car. Robots are streamlining

supply chains to deliver more efficient and predictable business results.

Positive impacts

– Supply chain and logistics, eliminations

– More leisure time

– Improved health outcomes (big data for pharmaceutical gains in research and development)

– Banking ATM as early adopter

– More access to materials

– Production “re-shoring” (i.e. replacing overseas workers with robots)

Negative impacts

– Job losses

– Liability, accountability

– Day-to-day social norms, end of 9-to-5 and 24-hour services

– Hacking and cyber-risk

Rethink Robotics released Baxter and received an overwhelming response from the manufacturing industry.

Later, Rethink launched a software platform that allows Baxter to do a more complex sequencing of tasks — for example, picking up a part, holding it in front of an inspection station and receiving a signal to place it in a ‘good’ or ‘not good’ pile. The company also released a software development kit … that will allow third parties — like university robotics researchers — to create applications for Baxter.”

Shift 16: Bitcoin and the Blockchain

The tipping point: 10% of global gross domestic product (GDP) stored on blockchain technology

By 2025: 58% of respondents expected this tipping point to have occurred

Bitcoin and digital currencies are based on the idea of a distributed trust mechanism called the

“blockchain”, a way of keeping track of trusted transactions in a distributed fashion. It has many use cases also in global supply chains, manufacturing and data monetization (IoTA).

Positive impacts

– Increased financial inclusion in emerging markets, as financial services on the blockchain gain critical

mass

– Disintermediation of financial institutions, as new services and value exchanges are created directly

on the blockchain

– An explosion in tradable assets, as all kinds of value exchange can be hosted on the blockchain

– Better property records in emerging markets, and the ability to make everything a tradable asset

– Contacts and legal services increasingly tied to code linked to the blockchain, to be used as

unbreakable escrow or programmatically designed smart contracts

– Increased transparency, as the blockchain is essentially a global ledger storing all transactions

Shift 17: The Sharing Economy

The tipping point: Globally more trips/journeys via car sharing than in private cars

By 2025: 67% of respondents expected this tipping point to have occurred

Well-known examples of the sharing economy exist in the transportation sector with companies like Zipcar, Uber, Lyft. The sharing economy has any number of ingredients, characteristics or descriptors: technology

enabled, preference for access over ownership, peer to peer, sharing of personal assets (versus

corporate assets), ease of access, increased social interaction, collaborative consumption and openly

shared user feedback (resulting in increased trust). Not all are present in every “sharing economy”

transaction.

Positive impacts

– Increased access to tools and other useful physical resources

– Better environmental outcomes (less production and fewer assets required)

– More personal services available

– Increased ability to live off cash flow (with less need for savings to be able to afford use of assets)

– Better asset utilization

– Less opportunity for long-term abuse of trust because of direct and public feedback loops

– Creation of secondary economies (Uber drivers delivering goods or food)

Negative impacts

– Less resilience after a job loss (because of less savings)

– More contract / task-based labour (versus typically more stable long-term employment)

– Decreased ability to measure this potentially grey economy

– More opportunity for short-term abuse of trust

– Less investment capital available in the system

Unknown, or cuts both ways

– Changed property and asset ownership

– More subscription models

– Fewer savings

– Lack of clarity on what “wealth” and “well off” mean

– Less clarity on what constitutes a “job”

– Difficulty in measuring this potentially “grey” economy

– Taxation and regulation adjusting from ownership/sales-based models to use-based models

Shift 18: Governments and the Blockchain

The tipping point: Tax collected for the first time by a government via a blockchain

By 2025: 73% of respondents expected this tipping point to have occurred

On the one hand, it is unregulated and not overseen by any central bank, meaning less control over monetary policy. On the other hand, it creates the ability for new taxing mechanisms to be built into the blockchain itself (e.g. a small transaction tax).

Unknown impacts, or cut both ways

– Central banks and monetary policy

– Corruption

– Real-time taxation

– Role of government

Shift 19: 3D Printing and Manufacturing

The tipping point: The first 3D-printed car in production

By 2025: 84% of respondents expected this tipping point to have occurred

3D printing, or additive manufacturing, is the process of creating a physical object by printing it layer

upon layer from a digital 3D drawing or model. Imagine creating a loaf of bread, slice by slice. 3D

printing has the potential to create very complex products without complex equipment. Eventually,

many different kinds of materials will be used in the 3D printer, such as plastic, aluminium, stainless

steel, ceramic or even advanced alloys, and the printer will be able to do what a whole factory was

once required to accomplish. It is already being used in a range of applications, from making wind

turbines to toys.

Over time, 3D printers will overcome the obstacles of speed, cost and size, and become more

pervasive.

Positive impacts

– Accelerated product development

– Reduction in the design-to-manufacturing cycle

– Easily manufactured intricate parts (not possible or difficult to do earlier)

– Rising demand for product designers

– Educational institutions using 3D printing to accelerate learning and understanding

– Democratized power of creation/manufacturing (both limited only by the design)

– Traditional mass manufacturing responding to the challenge by finding ways to reduce costs and the

size of minimum runs

– Growth in open-source “plans” to print a range of objects

– Birth of a new industry supplying printing materials

– The rise in entrepreneurial opportunities in the space96

– Environmental benefits from reduced transportation requirements

Negative impacts

– Growth in waste for disposal, and further burden on the environment

– Production of parts in the layer process that are anisotropic, i.e. their strength is not the same in all

directions, which could limit the functionality of parts

– Job losses in a disrupted industry

– Primacy of intellectual property as a source of value in productivity

– Piracy

– Brand and product quality

Unknown, or cuts both ways

– Potential that any innovation can be instantly copied

Shift 20: 3D Printing and Human Health

The tipping point: The first transplant of a 3D-printed liver

By 2025: 76% of respondents expected this tipping point to have occurred

One day, 3D printers may create not only things, but also human organs — a process called bioprinting.

In much the same process as for printed objects, an organ is printed layer by layer from a digital 3D

model. 3D printing has great potential to service custom design needs; and, there is nothing more custom than a human body.

Positive impacts

– Addressing the shortage of donated organs (an average of 21 people die each day waiting for

transplants that can’t take place because of the lack of an organ)98

– Prosthetic printing: limb/body part replacements

– Hospitals printing for each patient requiring surgery (e.g. splints, casts, implants, screws)

– Personalized medicine: 3D printing growing fastest where each customer needs a slightly different

version of a body part (e.g. a crown for a tooth)

– Printing components of medical equipment that are difficult or expensive to source, such as

transducers99

– Printing, for example, dental implants, pacemakers and pens for bone fracture at local hospitals

instead of importing them, to reduce the cost of operations

– Fundamental changes in drug testing, which can be done on real human objects given the availability

of fully printed organs

– Printing of food, thus improving food security

Negative impacts

– Uncontrolled or unregulated production of body parts, medical equipment or food

– Growth in waste for disposal, and further burden on the environment

– Major ethical debates stemming from the printing of body parts and bodies: Who will control the

ability to produce them? Who will ensure the quality of the resulting organs?

– Perverted disincentives for health: If everything can be replaced, why live in a healthy way?

– Impact on agriculture from printing food

In March 2015, leading scientists published a Nature article calling for a moratorium on editing human

embryos, highlighting “grave concerns regarding the ethical and safety implications of this research”.

Only one month later, in April 2015, “Researchers led by Junjiu Huang of Yat-sen University in

Guangzhou published the world’s first scientific paper on altering the DNA of human embryos.

Shift 21: 3D Printing and Consumer Products

The tipping point: 5% of consumer products printed in 3D

By 2025: 81% of respondents expected this tipping point to have occurred

Because 3D printing can be done by anyone with a 3D printer, it creates opportunities for typical

consumer products to be printed locally and on demand, instead of having to be bought at shops. A 3D

printer will eventually be an office or even a home appliance. This further reduces the cost of

accessing consumer goods and increases the availability of 3D printed objects. Current usage areas for

3D printing indicate several sectors related to developing and producing consumer

products (proof of concept, prototype and production).

Positive impacts

– Higher agricultural yields thanks to crops and crop treatments which are more robust, effective and

productive

– More effective medical therapies via personalised medicine

– Faster, more accurate, less invasive medical diagnostics

– Higher levels of understanding of human impact on nature

– Reduced incidence of genetic disease and related suffering

Negative impacts

– Risk of interaction between edited plants/animals human/environmental health

– Exacerbated inequality due to high cost of access to therapies

– Social backlash or rejection of gene editing technologies

– Misuse of genetic data by governments or companies

– International disagreements about ethical use of genome editing technologies

Unknown or cuts both ways

– Increased longevity

– Ethical dilemmas regarding nature of humanity

– Cultural shifts

We have counted 23 advances including the Designer Beings and Neurotechnologies we mentioned at the beginning. I wanted to list down the positive, negative and the grayish impacts to emphasize all the ethical aspects. Human — Machine interaction has always been a grift puzzle for sophisticated minds. Probably John Scalzi felt the same way when he was writing his famous novel, The Ghost Brigades:

Thank you, the BrainPal wrote. Your BrainPal™ will now be able to take direction from the sound of your voice. Would you like to personalize your BrainPal™ now?

“Yes,” I said.

Would you like to name your BrainPal™ at this time?

“Yes,” I said.

Please speak the name you would like to give your BrainPal™.

“ ‘Asshole,’ ” I said.

You have selected “Asshole,” the BrainPal wrote, and to its credit it spelled the word correctly.

Be aware that many recruits have selected this name for their BrainPal™. Would you like to choose a different name?

“No,” I said, and was proud that so many of my fellow recruits also felt this way about their BrainPal.

This is all for now. Next chapter will talk about some hands on applications of Idustry 4.0 which we introduced a bit in our recent post on our website.
