Balancing EdTech advancements with the essence of learning is crucial for realizing education's transformative potential.

Education sets humans apart from other species due to our ability to index, organize, and transmit knowledge to new generations. This allows young individuals to access our cultural and intellectual heritage, shaping the future of our society. Despite advancements in technology, there is still work to be done to make access to education universal and fully realize its transformative potential. The integration of technology in education, known as EdTech, has opened up new possibilities for personalizing content and evaluating the learning process. Multimedia resources, such as images, videos, and audio, can be recorded and made available online to millions of people. A prime example of this is the Khan Academy, which began as a personal project by electrical engineer Salman Khan in 2006 to help his cousins with their schoolwork. Today, it is used by tens of millions of students worldwide every month. The EdTech market is expected to reach approximately $340 billion in 2025, according to global education market intelligence firm HolonIQ. This growth is driven by the increasing demand for quality instruction and the labor market's need for more qualified professionals. EdTech companies are developing tools and methodologies to expand the reach of education and enhance its quality, thus contributing to a country's institutional and social evolution. However, the integration of technology in education also presents challenges. For instance, the learning process may become more difficult when technology plays a leading role, as it can lead to a lack of concentration and in-depth perception. American author Nicholas Carr's book, "The Shallows: What the Internet Is Doing to Our Brains," supports this notion, arguing that the barrage of information we face online hinders our ability to focus and learn effectively. In conclusion, the transformative potential of education and technology is immense, but it is crucial to strike a balance between leveraging technological advancements and preserving the essence of the learning process.

Unlocking value from big data across industries can revolutionize decision-making and generate billions in revenue.

Value extraction from information across various business segments has the potential to generate hundreds of billions of dollars in value. Both private and public sectors can benefit from the analyses performed by business intelligence systems, which process and analyze vast amounts of data to derive valuable insights. One example of value extraction can be seen in the analysis of social media data during a sporting event. With data coming in various forms (text, images, videos, audio) and from multiple sources (spectators, fans, reporters, players), proper analysis can lead to valuable insights for consumers and brands alike. This can help businesses make informed decisions, improve customer engagement, and drive revenue growth. Another example is the financial market, which generates massive amounts of information daily. The market's reaction to news stories, such as natural disasters, election results, or inflation rates, can impact asset prices. Artificial intelligence and big data techniques can analyze this data to predict market trends and inform investment strategies. In the public sector, big data can be used to improve public safety and infrastructure maintenance. For instance, by analyzing data on crime types, city events, weather, and people's movements, recommendations can be generated to help prevent crime and allocate resources more effectively. Similarly, analyzing data on infrastructure usage and wear can help prioritize maintenance and repairs, ultimately saving time and money. The key to unlocking the value in these diverse sectors lies in the ability to process and analyze massive amounts of data, often in real-time. As big data techniques continue to advance, the potential for value extraction across various industries will only grow, leading to more efficient and effective decision-making processes.

Information overload hinders effective learning by overwhelming short-term memory and impeding knowledge transmission to long-term memory.

Information overload has a significant impact on learning and decision-making processes. The constant barrage of information from various sources, such as websites with endless links, audio, video, comments, and ads, hinders our ability to process and absorb knowledge effectively. This is because our short-term memory is constantly distracted, trying to decide what to click on or pay attention to. For learning to occur, knowledge must be transmitted from short-term memory to long-term memory. The fewer interruptions and distractions our short-term memory faces, the more efficient this transmission will be. When we are bombarded with excessive stimulation, our capacity to store and connect new knowledge to what we already know is impeded. This lack of patience and focus is exacerbated by a culture of information overload, leading to a tendency to jump into easy and simple explanations or justifications. As Albert Einstein once said, "everything should be made as simple as possible, but not simpler." The impact of information overload on learning is further illustrated by a study conducted by Dr. Linda Henkel from the Department of Psychology at Fairfield University in Connecticut. She found that taking photos of art objects in a museum led to poorer memory of the objects' details and locations compared to not taking photos. This suggests that the hypothesis that taking pictures will help us remember events in our lives may not be true. Moreover, the reliance on technology for memory storage has significant implications, especially for children who have grown up with computers and smartphones. The learning process itself becomes more difficult when technology plays a leading role, as it often leads to interruptions and distractions that hinder concentration and in-depth perception.

Blockchain and encryption revolutionize data security, challenging centralized storage systems and transforming industries, while raising concerns about privacy and standardization.

Encryption and blockchain technologies play a crucial role in data storage and security, addressing the risks associated with centralized storage systems. Historically, confidential information has been stored in centralized locations with restricted access, such as the Great Library of Alexandria under Ptolemy I. However, these centralized systems present a clear target for potential attackers. Blockchain technology offers a decentralized and distributed solution for storing information, eliminating the need for a central authority and reducing the risk of hacking. Information is stored in chronological order, protected by cryptographic techniques and sophisticated mathematical functions. This makes it difficult, but not impossible, to edit the information once it is stored in a block. One example of blockchain's potential is Everledger, an English company that recorded nearly 1.5 million diamonds in a blockchain, storing information about their characteristics and origin. This helps prevent fraud and ensures the diamonds' provenance. Another example is the Kenyan government's use of blockchain to streamline the export process for flowers, improving security and efficiency. Despite the benefits of blockchain technology, there are still concerns about privacy, anonymity, legal backing, and technical standards. A Deloitte study found that 56% of executives believed establishing universal standards for blockchain implementation would be a game-changer, while 48% emphasized the need for legislation to ensure legal validity. Encryption is also essential for secure communication, with public key infrastructure (PKI) being the prevalent model. PKI guarantees that all parties in a communication are who they say they are, using a certification authority recognized by all participants. This hybrid model, combining symmetric and asymmetric encryption, ensures secure transactions over the internet.

Guy Perelmuter

Present Future explores the Deep Tech Revolution, examining the history and impact of key technological advances on various aspects of life, while preparing readers for the exponential leaps yet to come.

Key Ideas

The exponential growth of data in modern society can be traced back to the period between 1453 and 1503, when Eisenstein reported that approximately eight million books were printed, surpassing the total written material produced in the previous 5,000 years of civilization. Fast forward to the early 2020s, and it is estimated that each individual produces almost two megabytes of data per second. By 2025, the creation of 463 exabytes of data is expected every single day.

This massive increase in data creation presents a significant challenge: how to turn vast amounts of data, stored in various formats, into useful information. Big data techniques address this challenge by analyzing correlations among thousands of variables without knowing beforehand which ones will be relevant. Algorithms then extract necessary recommendations from these correlations.

In just three minutes, more than 10 million Google searches are performed, around 1.5 million new tweets are posted on Twitter, and 1 million new stories are posted to Instagram. Every day, more than 2.5 quintillion bytes of data are produced, equivalent to 2.5 million terabytes. With such a massive volume of data, the challenge lies in extracting relevant information and using it intelligently.

Big data techniques work by using all available data, often processing it in a distributed manner and in parallel by several processors. This allows for the extraction of value from information generated by different business segments, potentially worth hundreds of billions of dollars. Virtually all sectors, both private and public, that produce data can benefit from the analyses performed by business intelligence systems. For example, analyzing data from social media about a sporting event can provide valuable insights for consumers and brands.
