Debate: The Metaverse, flying taxis and other weapons of mass planetary destruction

Fabrice Flipo, Institut Mines-Télécom Business School

5G, 8K, flying taxis and the Metaverse are all topics of great interest, raising many questions. However, such questions are rarely, if ever, from an environmental perspective.

A recent article from French daily newspaper Le Monde, published October 18 2021 and titled “Facebook to hire 10,000 people in Europe to create the Metaverse”, discusses employment, the location of the innovation production site, “use cases” of this application and the experiences it will provide. However, the risks highlighted only relate to addiction or the rights of individuals in the Metaverse.

There is the same narrative framing on the topic of flying taxis, providing promises on the one hand and focusing on the user experience on the other.

In Toulouse, Airbus presents its flying taxi scheduled for 2023 (AFP, 2021).

However, the connection is never made between these initiatives and their potential impact on the biosphere. To find such a connection, you have to go to the “Environment” or “Books” sections of Le Monde: there, consumers are blamed for watching too many videos or sending too many emails.

This means of “compartmentalizing” debates and issues is nothing new – if you flick through old editions of Le Monde, you can find it again and again.

Hype technologies vs punitive environmentalism

Regulation works in the same way. On one side are laws and directives organizing the growth of digital technology and its applications; on the other are those that investigate the environmental implications of such technology, managed by other agencies, such as ADEME (the French Agency for Ecological Transition).

One of the main consequences of this division is making environmentalism appear “punitive”. On the one hand, we have technological innovations and related hype, promising new experiences, fun, happiness and incredible achievements. And on the other, the issue of the environment; discussing waste, energy efficiency, the destruction of the planet and other “depressing”, “boring” issues.

This also holds true for research: researchers with “new, good” technology are placed in the front row, with others left at the back. This is how the mediator at France Info explained that footballer Lionel Messi’s move to Paris Saint-Germain was “worth” more airtime than the report from the IPCC – the first topic was a longer-running story while the IPCC report was a one-off event.

Obliterating a more minimalist approach

Another consequence is that environmental regulation remains largely confined to the area of “energy efficiency”, a technical term referring to the amount of resources and energy needed to manufacture a good or provide a service.

This approach overshadows others, which are essential for the environmental transition – namely, approaches related to using less. Such approaches raise the question of whether we really need a certain good or service. Whether we are talking about 8K or 5G, the not-for-profit Shift Project questions the usefulness of these technologies in light of their forecasted effects on the planet.

The third consequence of this separation between digital expansion and environmental impact is that environmental policy is always struggling to catch up. We see this every day: despite regulation, the digital sector’s environmental impact continues to grow. Technologies are developed for millions or even billions of dollars. And only afterwards does the environmental question get raised. But by then, it is already too late!

Widespread dependencies… that could have been predicted

However, in a large number of cases, the effects of these projects are foreseeable – we can see well in advance which ideas will be disastrous, or at least highly problematic.

Thinking about this early on means we can avoid situations of technological lock-in, such as the widespread dependency on cars or smartphones in our current lifestyles. These are situations that are hard to get out of, as they require coordinating a change in infrastructure and habits, just like the use of bikes in cities “versus” cars.

We can see these easy-to-predict consequences with 5G, 8K, flying taxis and the Metaverse.

For example, 5G is designed to allow for a large increase in data transfer, but comes at a huge energetic cost, even if we have achieved increases in energy efficiency in this area since the 1950s that are just as significant. As emphasized by the Shift Project in their report, though increases in efficiency are stable at the technical level, they cannot compensate for the rise in data…

This reasoning also applies to 8K and the Metaverse, which is basically a conceptually similar, improved version of Second Life, a digital universe launched in 2003 that still exists today. At the time, technology specialist Nicholas Carr remarked that a Second Life avatar consumes about as much energy as the average Brazilian.

Works of fiction such as Virtual Revolution (2016) depict a world in which the Metaverse will absorb a key part of our social interactions, in the same way that social media is a major vehicle for daily conversations nowadays.

It is easy to predict the amount of information that will need to be produced and processed, compared with what exists already. IT company Cisco warns that these universes could easily become the biggest source of traffic on the internet.

As for flying taxis, their aim is to find space in the air that has been “lost” on the ground: in short, to clog up one of the last remaining spaces, despite the fact that moving up and down generally uses more energy than moving horizontally, due to gravity.

Our relationship to nature

We can see that it is not hard to establish the connection between technological innovation and the environmental situation, there is no conceptual difficulty here. And environmentalism does not always have to be lagging behind.

Back in Marx’s time, he explained that the question of humans’ relationship to nature is technical and so are our choices. It goes far beyond taking a blissful weekend stroll and admiring supposedly untouched areas…

Environmentalists have long been arguing that certain technological choices are incompatible with conditions for a good life on Earth. But these problems are formulated in the public sphere in a compartmentalized way, which prevents any serious discussion.

So what is the blockage?

Environmentalism does not have to be a “punitive” issue. Bike-riding, local products, renewable energy, insulation, DIY, and more… There are many environmental initiatives that can be discussed in the public sphere, as long as the various possible avenues are appropriately addressed.

So where is the issue? Why does hype benefit so many projects, when we can easily show that they will post huge problems once deployed on a certain scale? There are several explanations.

Tech projects receive the most funding, and are capable of a huge amount of impact in terms of persuasive power. They make use of marketing, surveys and other tools, perfectly dosing and precisely targeting their storytelling to reach the most receptive audiences, before progressively expanding to new fringes of the population, until they achieve saturation.

These selectively edited stories are also a part of the broader history of developed societies and their journey to create the most capital-intensive technologies, as Marx showed as early as 1867, emphasizing the effects of expanded reproduction of capital. Socialism also placed plenty of hope in this “expansion of productive forces”.

Moving away from this linear history, always pursuing the same aim, is seen as “moving backwards” and somehow, we would prefer to continue this narrative than preserve life on Earth. A narrative where science and science fiction combine, like Elon Musk announcing a future colony on Mars. Here, cognitive bias, known as the “Othello effect”, is at play.

Another explanation relates to capitalization itself, which represents a means of power for organizations. The greater the capitalization, the more the networks controlled by the organization will grow – and the greater the persuasive power. Elon Musk (yes, him again) aims to control the entire fleet of personal vehicles, with his robotaxis and self-driving cars. And what is true of companies is also true of governments, as highlighted by François Fourquet in his work “Les Comptes de la puissance” (The Accounts of Power).

While dominant ideas of socialism in the 20th century have always been fascinated by the collective power created by capitalism, trying to make it benefit as many as possible, environmentalism, on the other hand, supports decentralized initiatives and short circuits.

This trend often breaks with the “politics of power”, which explains in particular why conservatives are so opposed to it. Is it “realistic”, in a world where countries try to dominate each other? But on the other hand, can the leadership race last indefinitely if it undermines life on Earth?

IoT, Internet of Things

A standardized protocol to respond to the challenges of the IoT

The arrival of 5G has put the Internet of Things back in the spotlight, with the promise of an influx of connected objects in both the professional and private spheres. However, before witnessing the projected revolution, several obstacles remain. This is precisely what researchers at IMT Atlantique are working on, and they have already achieved results of global significance.

The Internet of Things (IoT) refers to the interconnection of various physical devices via the Internet for the purpose of sharing data. Sometimes referred to as the “Web 3.0”, this field is set to develop rapidly in the coming years, thanks to the arrival of new networks, such as 5G, and the proliferation of connected objects. Its applications are infinite: monitoring of health data, the connected home, autonomous cars, real-time and predictive maintenance on industrial devices, and more.

Although it is booming, the IoT still faces major challenges. “We need to respond to three main constraints: energy efficiency, interoperability and security,” explains Laurent Toutain, a researcher at IMT Atlantic. But there is one problem: these three aspects can be difficult to combine.

The three pillars of the IoT

First, energy is a key issue for the IoT. For most connected objects, the autonomy of a smartphone is not sufficient. In the future, a household may have several dozen such devices. If they each need to be recharged every two or three days, the user will have to devote several hours to this task. And what about factories that could be equipped with thousands of connected objects? In some cases, these are only of value if they have a long battery life. For example, a sensor could be used to monitor the presence of a fire extinguisher at its location and send an alert if it does not detect one. If you have to recharge its battery regularly, such an installation is no longer useful.

For a connected object, communication features account for the largest share of energy consumption. Thus, the development of IoT has been made possible by the implementation of networks, such as LoRa or Sigfox, allowing data to be sent while consuming little energy.

The second issue is interoperability, i.e. the ability of a product to work with other objects and systems, both current and future. Today, many manufacturers still rely on proprietary universes, which necessarily limits the functionalities offered by the IoT. Take the example of a user who has bought connected light bulbs from two different brands. They will not be able to control them via a single application.

Finally, the notion of security remains paramount within any connected system. This observation is all the more valid in the IoT, especially with applications involving the exchange of sensitive data, such as in the health sector. There are indeed many risks. An ill-intentioned user could intercept data during transmission, or send false information to connected objects, thus inducing wrong instructions, with potentially disastrous consequences.

On the Internet, methods are already in place to limit these threats. The most common is end-to-end data encryption. Its purpose is to make information unreadable while it is being transported, since the content can only be deciphered by the sender and receiver of the message.

Three contradictory requirements?

Unfortunately, each of the three characteristics can influence the others. For example, by multiplying the number of possible interlocutors, interoperability raises more security issues. But it also affects energy consumption. “Today, the Internet is a model of interoperability,” explains Laurent Toutain. For this, it is necessary to send a large amount of information each time, with a high degree of redundancy. It offers remarkable flexibility, but it also takes up a lot of space.” This is only a minor disadvantage for a broadband network, but not for the IoT, which is constrained in its energy consumption.

Similarly, if you want to have a secure system, there are two main possibilities. The first is to close it off from the rest of the ecosystem, in order to reduce risks, which radically limits interoperability.

The second is to implement security measures, such as end-to-end encryption, which results in more data being sent, and therefore increased energy consumption.

Reducing the amount of data sent, without compromising security

For about seven years, Laurent Toutain and his teams have been working to reconcile these different constraints, in the context of the IoT. “The idea is to build on what makes the current Internet so successful and adapt it to the constrained environments, says the researcher. We are therefore taking up the principles of the encryption methods and protocols used today, such as HTTP, but taking into account the specific requirements of the IoT”.

The research team has developed a compression mechanism named SCHC (Static Context Header Compression, pronounced “chic”). It aims to improve the efficiency of encryption solutions and provide interoperability in low-power networks.

For this purpose, SCHC works on the headers of the usual Internet protocols (IP, UDP and CoAP), which contain various details: source address, destination address, location of the data to be read, etc. The particularity of this method is that it takes advantage of the specificity of the IoT: a simple connected object, such as a sensor, has far fewer functions than a smartphone. It is then possible to anticipate the type of data sent. “We can thus free ourselves from the redundancy of classic exchanges on the web, says Laurent Toutain. We then lose flexibility, which could be inconvenient for standard Internet use, but not for a sensor, which is limited in its applications”.

In this way, the team at IMT Atlantique has achieved significant results. It has managed to reduce the size of the headers traditionally sent, weighing 70-80 bytes, to only 2 bytes, and to 10 bytes in their encrypted version. “A quantity that is perfectly acceptable for a connected object and compatible with network architectures that consume very little energy,” concludes the researcher.

A protocol approved by the IETF

But what about that precious interoperability? With this objective, the authors of the study approached the IETF (Internet Engineering Task Force), the international organization for Internet standards. The collaboration has paid off, as SCHC has been approved by the organization and now serves as the global standard for compression. This recognition is essential, but is only a first step towards effective interoperability. How can we now make sure that manufacturers really integrate the protocol into their connected objects? For this, Laurent Toutain has partnered with Alexander Pelov, also a researcher at IMT Atlantic, in order to found the start-up company Acklio. The company works directly with industrialists and offers them solutions to integrate SCHC in their products. It thus intends to accelerate the democratization of the protocol, an effort supported in particular by  €2 million in funds raised at the end of 2019.

Nevertheless, industrialists remain to be convinced that the use of a standard is also in their interest. To this end, Acklio also aims to position SCHC among the protocols used within 5G. To achieve this, it will have to prove itself with the 3GPP (3rd Generation Partnership Project) which brings together the world’s leading telecommunications standards bodies. “A much more constraining process than that of the IETF,” however, warns Laurent Toutain.
