Is AI - combined with more smartphone use, social media, pandemic and other disruptions - reducing our ability to learn?



From page 13 "The threat of cognitive offloading is particularly acute 
amid already declining learning outcomes. Even before the introduction of mass commercial AI tools (2022) the OECD’s Programme for International Student Assessment (PISA) data showed substantial declines in student performance in mathematics, reading and science since the early 2010s (Figure
5). 

Adults are not immune: the OECD’s 2024 Survey of Adult Skills found literacy declining in 11 countries and falling among tertiary-educated adults in thirteen. These trends reflect a complex interplay of factors, including increased smartphone use, social media, pandemic and other disruptions. 

Against this backdrop, AI may exacerbate existing weaknesses by reducing opportunities for active cognitive engagement rather than being the primary cause of these declines."

The Digital Revolution: Transforming Our World through Data Digitization

Introduction - In today's rapidly evolving technological landscape, the digitization of data has emerged as a transformative force, reshaping industries, governments, and societies worldwide. The process of converting analog information into digital format has not only streamlined operations but has also unlocked countless opportunities for innovation, efficiency, and progress.

From Analog to Digital: A Brief History

The journey of digitization traces back to the mid-20th century when computers first became capable of storing and processing information in binary code, essentially ones and zeros. Prior to this digital age, data was predominantly analog, residing in handwritten documents, physical photographs, vinyl records, and more. These analog forms were not only less efficient to manage but also susceptible to wear, damage, and loss.

The transition to digital data marked a profound shift. It allowed information to be stored, manipulated, and transmitted with unparalleled speed, accuracy, and durability. This revolution brought forth the birth of the digital era, and its impact has been nothing short of revolutionary.

The Digital Data Boom

In recent decades, the digitization of data has witnessed an explosive growth rate. This surge is attributed to several factors, including the advent of the internet, the proliferation of smart devices, and the rise of cloud computing. Today, we generate massive volumes of data through various sources such as social media, e-commerce transactions, sensor-equipped devices, and more. This avalanche of data, often referred to as "big data," presents both challenges and opportunities.

The Power of Digitized Data - The digitization of data has empowered individuals, organizations, and governments in numerous ways:

Efficiency and Accessibility: Digital data is easily stored, retrieved, and shared, eliminating the need for physical storage and reducing the time and effort required to access information. This has streamlined operations in businesses, healthcare, education, and beyond.

Data Analysis: Digitized data can be subjected to advanced analytics and machine learning algorithms, revealing insights and patterns that were previously hidden. This has revolutionized decision-making processes across industries, enabling data-driven strategies.

Global Connectivity: The internet and digital data have connected people across the globe, transcending geographical boundaries. This connectivity has enabled remote work, online education, telemedicine, and global collaboration on an unprecedented scale.

Innovation: Digitization has paved the way for innovative technologies like artificial intelligence, virtual reality, and the Internet of Things (IoT), which are transforming industries and creating new economic opportunities.

Preservation: Digital data can be archived and preserved for extended periods without degradation, ensuring the long-term conservation of historical records, cultural heritage, and scientific knowledge.

Environmental Impact: Although data centers consume energy, digital data often reduces the need for physical resources like paper, reducing environmental impact.

Challenges and Concerns - Despite its many advantages, the digitization of data also presents challenges, including issues related to data privacy, security, and the digital divide. Protecting sensitive information and ensuring equitable access to technology are critical considerations as we continue to digitize our world.

In conclusion - the digitization of data has profoundly transformed the way we live, work, and interact with the world around us. It has unlocked unprecedented possibilities for innovation and efficiency, shaping the future in ways that were once unimaginable. As we navigate the digital age, it is essential to harness the power of digitized data responsibly and ethically, ensuring that its benefits are shared equitably across society.

Twitter thread from @RobertGReeve - you're social media #apps aren't #listening to you - but frankly they don't need to


So compared with stuff where you do the listening, here's what happens when you're on the internet ...Source and HT to  https://twitter.com/RobertGReeve/status/1397032784703655938


"First of all, your social media apps are not listening to you. This is a conspiracy theory. It's been debunked over and over again.

But frankly they don't need to because everything else you give them unthinkingly is way cheaper and way more powerful.  Your apps collect a ton of data from your phone. Your unique device ID. Your location. Your demographics. 

Data aggregators pay to pull in data from EVERYWHERE. When I use my discount card at the grocery store? Every purchase? That's a dataset for sale.  They can match my Harris Teeter purchases to my Twitter account because I gave both those companies my email address and phone number and I agreed to all that data-sharing when I accepted those terms of service and the privacy policy. 

Here's where it gets truly nuts, though.  If my phone is regularly in the same GPS location as another phone, they take note of that. They start reconstructing the web of people I'm in regular contact with.

The advertisers can cross-reference my interests and browsing history and purchase history to those around me. It starts showing ME different ads based on the people AROUND me.  Family. Friends. Coworkers.

It will serve me ads for things I DON'T WANT, but it knows someone I'm in regular contact with might want. To subliminally get me to start a conversation about, I don't know, fucking toothpaste.  It never needed to listen to me for this. It's just comparing aggregated metadata.

The other thing is, this is just out there in the open. Tons of people report on this. It's just, nobody cares. We have decided our privacy just isn't worth it. It's a losing battle. We've already given away too much of ourselves.

Your data isn't just about you. It's about how it can be used against every person you know, and people you don't. To shape behavior unconsciously."

6min 40sec @theeconomist clip - How #data transformed the #NBA


Text from youtube "Data analytics is changing the way professional basketball in North America is played. 

NBA teams like the Houston Rockets are tracking data on player performances to gain a competitive edge over their rivals in this multi-billion dollar sport. An invisible powerful force is lifting professional basketball to new heights, transforming how this multibillion-dollar sport is played and, crucially how to win. 

In elite sport the difference between success and failure is often the finest of margins. The Houston Rockets are one of the top teams in NBA basketball. They boast some of the sport's biggest stars, including the NBA's most valuable player in 2018. 

 In the past decade the Rockets have risen from mid-table mediocrity to serious NBA championship contenders. But it's not just big names that have fueled this dramatic ascent - it's big data.

13min @thecrashcourse clip - #Data & #Infographics: Navigating Digital Information #8



text from youtube "Today, we're going to discuss how numbers, like statistics, and visual representations like charts and infographics can be used to help us better understand the world or profoundly deceive. Data is a really powerful form of evidence because it can be absorbed quickly and easily, but neither data, nor interpretations of it, are neutral, so today we're going to discuss how to think critically about the statistics we encounter in everyday life.

11min24se @thecrashcourse clip - Henrietta Lacks, the #Tuskegee Experiment, & #Ethical #Data Collection: Crash Course Statistics #12

 
Text from youtube " ... we’re going to talk about ethical data collection. From the Tuskegee syphilis experiments and Henrietta Lacks’ HeLa cells to the horrifying experiments performed at Nazi concentration camps, many strides have been made from Institutional Review Boards (or IRBs) to the Nuremberg Code to guarantee voluntariness, informed consent, and beneficence in modern statistical gathering. But as we’ll discuss, with the complexities of research in the digital age many new ethical questions arise. "

11min 22sec @TheCrashCourse clip - The Shape of #Data: #Distributions : Crash Course Statistics #7


Text from youtube "When collecting data to make observations about the world it usually just isn't possible to collect ALL THE DATA. So instead of asking every single person about student loan debt for instance we take a sample of the population, and then use the shape of our samples to make inferences about the true underlying distribution our data.

It turns out we can learn a lot about how something occurs, even if we don't know the underlying process that causes it. Today, we’ll also introduce the normal (or bell) curve and talk about how we can learn some really useful things from a sample's shape - like if an exam was particularly difficult, how often old faithful erupts, or if there are two types of runners that participate in marathons!
