A New Web Could be Coming. Will It Improve Human Health?
A number of emerging technologies are in the mix to define Web3, the next era of the digital age. They could contribute to our overall health and well-being.
The Web has provided numerous benefits over the years, but users have also experienced issues related to privacy, cybersecurity, income inequality, and addiction which negatively impact their quality of life. In important ways, the Web has yet to meet its potential to support human health.
Now, engineers are in the process of developing a new version of the Web, called Web3, which would seek to address the Web’s current shortcomings through a mix of new technologies.
It could also create new problems. Industrial revolutions, including new versions of the Web, have trade-offs. While many activists tend to focus on the negative aspects of Web3 technologies, they overlook some of the potential benefits to health and the environment that aren’t as easily quantifiable such as less stressful lives, fewer hours required for work, and a higher standard of living. What emerging technologies are in the mix to define the new era of the digital age, and how will they contribute to our overall health and well-being?
In order to answer these questions, I have identified three major trends that may help define the future landscape of Web3. These include more powerful machine intelligence that could drive improvements in healthcare, decentralized banking systems that allow consumers to bypass middlemen, and self-driving cars with potential to reduce pollution. However, it is the successes of the enabling technologies that support these goals—improvements in AI, blockchain and smart contracts, and fog computing—that will ultimately define Web3.
Machine Intelligence and Diagnosing Diseases
While the internet is the physical network equipment and computers that keep the world connected, the Web is one of the services that run on the internet. In 1989, British scientist Tim Berners-Lee invented the World Wide Web and, when Web1 went live in 1991, it consisted of pages of text connected by hyperlinks. It remained that way until 2004 with the introduction of Web2, which provided social media websites and let users generate content in addition to consuming it passively.
The Semantic Web could expand the impact of new cognitive skills for machines by feeding data to AI in more readily accessible formats. This will make machines better at solving hard problems such as diagnosing and treating complex diseases.
For the most part, Web2 is what we still have today but, from the beginning, Berners-Lee, now an MIT professor, envisaged a much more sophisticated version of the Web. Known as the Semantic Web, it would not only store data, but actually know what it means. The goal is to make all information on the Internet “machine-readable,” so it can be easily processed by computers, like an Excel sheet full of numbers as opposed to human language. We are now in the early stages of the Semantic Web, which incorporates his vision. For example, there is already a cloud of datasets that links thousands of servers without any form of centralized control. However, due to the costs and technological hurdles related to converting human language into something that computers can understand, the Semantic Web remains an ongoing project.
Currently, AI is only able to perform certain tasks, but it can already make healthcare business practices more efficient by leveraging deep learning to analyze data in supply chains. DeepMind, the company that developed AI for defeating chess masters, has also made huge advances in figuring out protein folding and misfolding, which is responsible for some diseases. Currently, AI is not that useful for diagnosing and treating many complex diseases. This is because deep learning is probabilistic, not causal. So, it is able to understand correlation, but not cause and effect.
Like the Web, though, AI is evolving, and the limitations of deep learning could be overcome in the foreseeable future. A number of government programs and private initiatives are dedicated to better understanding human brain complexity and equipping machines with reasoning, common sense, and the ability to understand cause and effect. The Semantic Web could expand the impact of these new cognitive skills by feeding data to AI in more readily accessible formats. This will make machines better at solving hard problems such as diagnosing and treating complex diseases, which involve genetic, lifestyle, and environment factors. These powerful AIs in the realm of healthcare could become an enduring and important feature of Web3.
Blockchain, Smart Contracts and Income Inequality
The Web2 version of the digital age was certainly impactful in altering our lifestyle both positively and negatively. This is predominately because of the business model used by companies such as Meta (formerly Facebook) and Google. By providing useful products like search engines, these companies have lured consumers into giving away their personal data for free, and the companies use this information to detect buying patterns in order to sell advertising. The digital economy made high tech companies billions of dollars while many users became underemployed or jobless.
In recent years, a similar model has been emerging in the realm of genetics. Personalized genomic companies charge a relatively small fee to analyze a fraction of our genes and provide probabilities of having specific medical conditions. While individual data is not valuable, cumulative data is helpful for deep learning. So, these companies can sell the anonymous DNA data to pharmaceutical companies for millions of dollars.
As these companies improve their ability to collect even more data about our genetic vulnerabilities, the technologies of Web3 could protect consumers from giving it away for free. An emerging technology called blockchain is able to provide a Web-based ledger of financial transactions with checks and balances to ensure that its records cannot be faked or altered. It has yet to reach mass adoption by the public, but the computer scientist Jaron Lanier has proposed storing our genomes and electronic health records in blockchain, utilizing electronic smart contracts between individuals and pharma healthcare industry. Micropayments could then be made to individuals for their data, using cryptocurrency.
These individual payments could become more lucrative in the coming years especially as researchers learn how to fully interpret and apply a person’s genetic data. In this way, blockchain could lead to improvements in income inequality, which currently drives health problems and other challenges for many. A number of start-ups are using this business model which has secure data and eliminates middlemen who don’t create any value, while compensating and protecting the privacy of individuals who contribute their health data.
Autonomous Vehicles, Fog Computing and Pollution
A number of trends indicate that modernizing the transportation industry would address a myriad of problems with public health, productivity and the environment. Autonomous vehicles (AVs) could help usher in this new era of transportation, and these AVs would need to be supported by Web3 technologies.
Automobile accidents are the second leading cause of death worldwide, with roughly 1.3 million fatalities annually, according to the World Health Organization. Some estimates suggest that replacing human drivers with AVs could eliminate as many as a million global fatalities annually. Shared AVs would help to reduce traffic congestion that wastes time and fuel, and electric vehicles would help minimize greenhouse gases.
To reap the benefits from replacing gas vehicles with electric, societies will need an infrastructure that enables self-driving cars to communicate with each other. Most data processing in computers is performed using von Neumann architecture, where the data memory and the processor are in two different places. Today, that typically means cloud computing. With self-driving cars, when cameras and sensors generate data to detect objects on the roads, processors will need to rapidly analyze the data and make real-time decisions regarding acceleration, braking, and steering. However, cloud computing is susceptible to latency issues.
One solution to latency is moving processing and data storage closer to where it is needed to improve response times. Edge computing, for example, places the processor at the site where the data is generated. Most new human-driven vehicles contain anywhere from 30 to 100 electronic control units (ECUs) that process data and control electrical systems in vehicles. These embedded systems, typically in the dashboard, control different applications such as airbags, steering, brakes, etc. ECUs process data generated by cameras and sensors in AVs and make crucial decisions on how they operate.
Self-driving cars can benefit by communicating with each other for navigation in the same way that bacteria and animals use swarm intelligence for tasks involving groups. Researchers are currently investigating fog computing which utilizes servers along highways for faster and more reliable navigation and for communicating data analytics among driverless cars.
The Future Landscape of Web3 is Uncertain
The future of Web3 has many possibilities. However, there is no guarantee that blockchain, smart contracts, and fog computing will achieve public acceptance and market saturation or prevail over other technologies or the status quo of Web2. It is also uncertain if or when the breakthroughs in AI will occur that could eradicate complex diseases through Web3.
An example of this uncertainty is the metaverse, which combines blockchain with virtual reality. Currently, the metaverse is primarily used for gaming and recreational use until its infrastructure is further developed. Researchers are interested in the long-term mental health effects of virtual reality, both positive and negative. Using avatars, or virtual representations of humans, in the metaverse, users have greater control of their environment and chosen identities. But, it is unclear what negative mental health effects will occur. As far as regulations, the metaverse is still in the Wild West stage, and bullying or even murder will likely take place. Also, there will be a point where virtual worlds like the metaverse will become so immersive that we won't want to leave them, according to Meta’s Zuckerberg.
The metaverse would rely on virtual reality technology that was developed many years ago, and adoption has been slower than some experts predicted. But most emerging technologies, including other examples related to Web3, follow a similar, nonlinear pattern of development that Gartner has represented in graphical form using the S-curve. To develop a technology forecast for Web3, you can follow the progress along the curve from proof of concept to a particular goal. After a series of successes and failures, entrepreneurs will continue to improve their products until each emerging technology fails or achieves mainstream adoption by the public.
What mix of emerging technologies ultimately defines Web3 will likely be determined by the benefits they provide to society—including whether and how they improve health—how they stimulate the digital economy, and how they address the significant shortcomings of Web2.
After his grandmother’s dementia diagnosis, one man invented a snack to keep her healthy and hydrated.
Founder Lewis Hornby and his grandmother Pat, sampling Jelly Drops—an edible gummy containing water and life-saving electrolytes.
On a visit to his grandmother’s nursing home in 2016, college student Lewis Hornby made a shocking discovery: Dehydration is a common (and dangerous) problem among seniors—especially those that are diagnosed with dementia.
Hornby’s grandmother, Pat, had always had difficulty keeping up her water intake as she got older, a common issue with seniors. As we age, our body composition changes, and we naturally hold less water than younger adults or children, so it’s easier to become dehydrated quickly if those fluids aren’t replenished. What’s more, our thirst signals diminish naturally as we age as well—meaning our body is not as good as it once was in letting us know that we need to rehydrate. This often creates a perfect storm that commonly leads to dehydration. In Pat’s case, her dehydration was so severe she nearly died.
When Lewis Hornby visited his grandmother at her nursing home afterward, he learned that dehydration especially affects people with dementia, as they often don’t feel thirst cues at all, or may not recognize how to use cups correctly. But while dementia patients often don’t remember to drink water, it seemed to Hornby that they had less problem remembering to eat, particularly candy.
Where people with dementia often forget to drink water, they're more likely to pick up a colorful snack, Hornby found. alzheimers.org.uk
Hornby wanted to create a solution for elderly people who struggled keeping their fluid intake up. He spent the next eighteen months researching and designing a solution and securing funding for his project. In 2019, Hornby won a sizable grant from the Alzheimer’s Society, a UK-based care and research charity for people with dementia and their caregivers. Together, through the charity’s Accelerator Program, they created a bite-sized, sugar-free, edible jelly drop that looked and tasted like candy. The candy, called Jelly Drops, contained 95% water and electrolytes—important minerals that are often lost during dehydration. The final product launched in 2020—and was an immediate success. The drops were able to provide extra hydration to the elderly, as well as help keep dementia patients safe, since dehydration commonly leads to confusion, hospitalization, and sometimes even death.
Not only did Jelly Drops quickly become a favorite snack among dementia patients in the UK, but they were able to provide an additional boost of hydration to hospital workers during the pandemic. In NHS coronavirus hospital wards, patients infected with the virus were regularly given Jelly Drops to keep their fluid levels normal—and staff members snacked on them as well, since long shifts and personal protective equipment (PPE) they were required to wear often left them feeling parched.
In April 2022, Jelly Drops launched in the United States. The company continues to donate 1% of its profits to help fund Alzheimer’s research.
Theupcoming vaccine is changing the way we look at treating one of the country’s deadliest cancers.
Last week, researchers at the University of Oxford announced that they have received funding to create a brand new way of preventing ovarian cancer: A vaccine. The vaccine, known as OvarianVax, will teach the immune system to recognize and destroy mutated cells—one of the earliest indicators of ovarian cancer.
Understanding Ovarian Cancer
Despite advancements in medical research and treatment protocols over the last few decades, ovarian cancer still poses a significant threat to women’s health. In the United States alone, more than 12,0000 women die of ovarian cancer each year, and only about half of women diagnosed with ovarian cancer survive five or more years past diagnosis. Unlike cervical cancer, there is no routine screening for ovarian cancer, so it often goes undetected until it has reached advanced stages. Additionally, the primary symptoms of ovarian cancer—frequent urination, bloating, loss of appetite, and abdominal pain—can often be mistaken for other non-cancerous conditions, delaying treatment.
An American woman has roughly a one percent chance of developing ovarian cancer throughout her lifetime. However, these odds increase significantly if she has inherited mutations in the BRCA1 or BRCA2 genes. Women who carry these mutations face a 46% lifetime risk for ovarian and breast cancers.
An Unlikely Solution
To address this escalating health concern, the organization Cancer Research UK has invested £600,000 over the next three years in research aimed at creating a vaccine, which would destroy cancerous cells before they have a chance to develop any further.
Researchers at the University of Oxford are at the forefront of this initiative. With funding from Cancer Research UK, scientists will use tissue samples from the ovaries and fallopian tubes of patients currently battling ovarian cancer. Using these samples, University of Oxford scientists will create a vaccine to recognize certain proteins on the surface of ovarian cancer cells known as tumor-associated antigens. The vaccine will then train that person’s immune system to recognize the cancer markers and destroy them.
The next step
Once developed, the vaccine will first be tested in patients with the disease, to see if their ovarian tumors will shrink or disappear. Then, the vaccine will be tested in women with the BRCA1 or BRCA2 mutations as well as women in the general population without genetic mutations, to see whether the vaccine can prevent the cancer altogether.
While the vaccine still has “a long way to go,” according to Professor Ahmed Ahmed, Director of Oxford University’s ovarian cancer cell laboratory, he is “optimistic” about the results.
“We need better strategies to prevent ovarian cancer,” said Ahmed in a press release from the University of Oxford. “Currently, women with BRCA1/2 mutations are offered surgery which prevents cancer but robs them of the chance to have children afterward.
Teaching the immune system to recognize the very early signs of cancer is a tough challenge. But we now have highly sophisticated tools which give us real insights into how the immune system recognizes ovarian cancer. OvarianVax could offer the solution.”
