With the invention of the transistor, the challenge shifted to manufacturing them reliably and at scale. William Shockley, driven by ambition and a desire for wealth, established Shockley Semiconductor in California. However, his poor management skills and toxic work environment led to the departure of eight talented engineers - The Traitorous Eight - who would go on to found Fairchild Semiconductor and play a pivotal role in the development of Silicon Valley.

Jack Kilby, an engineer at Texas Instruments, focused on simplifying the complexity of wiring multiple transistors together. In 1958, he developed the concept of the "integrated circuit," where multiple transistors could be built on a single piece of semiconductor material, eliminating the need for extensive wiring. This invention, later known as the "chip," marked a significant breakthrough in miniaturization and efficiency.

By the late 2010s, ASML had spent nearly two decades perfecting extreme ultraviolet lithography (EUV). EUV was crucial for the continuation of Moore's Law, which predicted the exponential growth in the number of transistors on a chip. Existing lithography methods using deep ultraviolet light were reaching their limit and couldn't produce the even smaller circuits needed for next-generation semiconductors. EUV, with a much smaller wavelength, was the only viable path forward. The development of EUV was an incredibly complex engineering feat requiring collaboration from companies around the world to source the most advanced components, purest metals, and most powerful lasers.
Implementing EUV lithography presented several challenges that pushed the limits of engineering. Creating an EUV light source required blasting tiny tin droplets with a laser fifty thousand times per second. This process generated immense heat and required a specialized laser system that took a decade to develop. Additionally, EUV light is difficult to reflect, necessitating the creation of the smoothest mirrors ever made, constructed from alternating layers of molybdenum and silicon, each just a couple of nanometers thick.

The chip industry's landscape has undergone significant changes, moving away from the traditional model of integrated design and manufacturing within a single company. Foundries like TSMC have emerged, offering chip fabrication services to fabless companies that focus solely on design. This shift is driven by the increasing cost and complexity of building and operating fabs, as each generation of technological advancement requires more expensive equipment and expertise.
However, some industry veterans like Jerry Sanders, founder of AMD, remain staunch advocates of the integrated model, believing that owning fabs is essential for maintaining control and ensuring quality. He famously quipped, "Real men have fabs," reflecting a cultural attachment to the traditional way of doing things. However, the economic realities and the success of fabless companies are challenging this mindset.

The invention of the vacuum tube marked a significant step forward in computing. By using electrical charges that could be switched on and off, vacuum tubes could represent 1s and 0s, the foundation of binary code. Unlike mechanical gears, vacuum tubes could be reprogrammed, allowing for greater flexibility in calculations. However, the limitations of vacuum tubes, including their size, unreliability, and attraction to moths, made it clear that a more efficient switch was needed.

The 1990s marked a turning point for Taiwan's role in the semiconductor industry. Recognizing the limitations of being primarily an assembly hub, Taiwan's leaders, particularly K.T. Li, sought to move towards higher-value chip fabrication. This strategic shift was driven by several factors, including the need to stay ahead of China's growing manufacturing capabilities and the desire to capture a larger share of the industry's profits. The establishment of TSMC, spearheaded by Morris Chang, was central to this vision. TSMC's innovative foundry model, which focused solely on manufacturing chips designed by other companies, revolutionized the industry and propelled Taiwan to the forefront of advanced chip production.

The dot-com crash in the early 2000s taught Silicon Valley four main lessons:
- Make incremental advances
- Stay lean and flexible
- Improve on the competition
- Focus on product, not sales
However, the opposite principles are probably more correct:
- It's better to risk boldness than triviality
- A bad plan is better than no plan
- Competitive markets destroy profits
- Sales matters just as much as product
The need for new technology is greater now than ever before. But we won't get it if everyone focuses on incremental improvements.

Many people worry that computers will put people out of work. But in reality, technology is improving productivity and helping people do higher-leverage work. In many fields, the most valuable companies are those that combine the strengths of computers and humans:
- Palantir uses AI to flag suspicious activity but has human analysts make judgment calls
- LinkedIn uses automated data aggregation but human curation and editing
- Hybrid human-computer solutions are underrated relative to complete automation
Instead of trying to replace people entirely, the most valuable companies will ask "How can computers help humans solve hard problems?"

Even as humanism faces existential threats from AI, a new ideology is emerging that may come to dominate our century - Dataism. Its central tenets are:
- Data is the supreme value - the world consists of data flows, and the value of any phenomenon lies in its contribution to data processing. From this perspective: An organism is simply an algorithm and its value lies in processing data; A society is a system for harvesting and analyzing data.
- Humans are no longer the most important data processors - the baton is passing to computers, which are far better at crunching information than biological brains. As AI advances, algorithms will know us better than we know ourselves, making human decision-making obsolete. Humans will merge with technology to stay relevant, blurring the line between organic and artificial intelligence
- Bringing more and more data online is the supreme good - information wants to be free. All barriers to the flow of data should be removed. Privacy is theft from the data commons, free speech and transparency are sacred, and expanding the internet of things is a moral imperative

Imagine this scenario: a married woman starts an affair with a coworker. She is careful not to leave any obvious traces, but the signs are there if you know how to look:
- Location tracking on her phone shows frequent visits to hotels near the office
- Her search history includes "how to hide an affair" and "signs your partner is cheating"
- Her social media posts depict a happy marriage, but facial recognition AI detects micro-expressions of doubt and unease
Thanks to the power of big data and machine learning, companies like Google and Facebook can connect the dots to infer even our most intimate secrets - often without us realizing it.
This example illustrates a stark reality: in the digital age, privacy is becoming a relic of the past. No matter how carefully we curate our online image, the truth leaks out in a thousand data points we scatter in our wake.

Technology-powered products that the book focuses on span a wide range, including:
- Consumer-service products (e.g. Netflix, Airbnb, Etsy)
- Social media (e.g. Facebook, LinkedIn, Twitter)
- Business services (e.g. Salesforce, Workday)
- Consumer devices (e.g. Apple, Sonos, Tesla)
- Mobile apps (e.g. Uber, Instagram)
The definition of "product" is very holistic, including not just features but the enabling technology, user experience design, monetization, customer acquisition, and offline experiences essential to delivering the product's value.

The authors use the historical example of the slow adoption of electricity to illustrate the challenges of deploying a new general purpose technology like AI. They describe three types of entrepreneurs that tried to exploit electricity in different ways in the late 19th/early 20th century:
- Point solution entrepreneurs who simply replaced steam power with electric power with minimal factory redesign. This provided limited benefits.
- Application solution entrepreneurs who redesigned individual machines and tools around electric motors. This enabled some new capabilities but still limited benefits without factory redesign.
- System solution entrepreneurs who completely redesigned factories to fully exploit the unique advantages of electric power. This is what ultimately transformed manufacturing and the economy, but it took decades.
Section: 1, Chapter: 1
The authors argue that AI is a general purpose technology (GPT) like electricity and the steam engine that has the potential to transform the economy over time. However, as with past GPTs, there is a significant delay between the initial invention and demonstration of the technology and its widespread adoption and impact on productivity. The authors refer to this delay as "The Between Times." During this period, point solutions and application solutions emerge, but the big productivity gains come only later with the development of system solutions that more fully exploit the technology's potential.
Section: 1, Chapter: 2
The authors argue that the essence of recent advances in AI is that they represent a dramatic improvement in prediction - the ability to take information you have and generate information you don't have. Prediction is a key input into decision making. As prediction becomes cheaper, we will use more of it and the value of other inputs to decision making like human prediction will fall while the value of complements like data and judgment will rise. Judgment is determining the relative payoff or reward to different actions - it is a statement of what we want, while prediction tells us the likelihood of different outcomes.

"Predicting on the support of your data is not as simple as collecting data from a wider variety of settings to ensure you aren't extrapolating too much or avoiding predicting too far into the future. Sometimes the data you need doesn't exist. This underlies the refrain repeated in every statistics course worldwide: correlation is not necessarily causation."

Airport operators should be wary of the disruptive potential of AI-powered navigation apps like Waze and Google Maps. Key considerations:
- These apps can provide increasingly accurate, personalized predictions of travel time to the airport, reducing the need for passengers to budget large uncertainty buffers
- As passengers become more confident in "just in time" airport arrival, demand for in-terminal retail and dining may fall significantly
- Airport operators should explore ways to actively partner with navigation apps to shape behavior and preserve retail revenues, rather than being passive victims of disruption
