Release Date: December 13, 2024
Host: Bel Lin | The Wall Street Journal

1. Introduction

In this episode of the WSJ Tech News Briefing, host Bel Lin delves into two major topics shaping the tech landscape: the evolving race in the autonomous vehicle industry, particularly focusing on Waymo and its competitor Cruise, and the burgeoning field of artificial intelligence (AI) with an emphasis on its "long thinking" capabilities. The episode provides insightful analysis, expert opinions, and future projections that are essential for understanding current and upcoming technological advancements.

2. Waymo’s Ascendancy in the Autonomous Vehicle Market

a. Cruise's Shutdown and Its Impact on Waymo

The episode opens with significant news in the autonomous vehicle sector: General Motors (GM) has decided to shut down its robo-taxi program, Cruise, citing intense competition, escalating costs, and the challenges of scaling the business. This development marks a pivotal moment for Waymo, Alphabet's driverless car subsidiary, positioning it to further dominate the robo-taxi industry.

Notable Quote:
"This is a really big opportunity for Waymo and it widens their lead in the robo taxi industry even more than they already had been."
— Danny Lewis, Reporter [01:59]

Danny Lewis explains that Cruise had been a formidable competitor until an incident in October 2023, where a Cruise-operated driverless car struck a pedestrian in San Francisco, leading to severe regulatory setbacks. Despite efforts to revive their services, GM found the endeavor financially unsustainable and opted to discontinue Cruise's operations.

b. Waymo’s Expansion Plans and Future Prospects

With Cruise exiting the arena, Waymo is poised to capitalize on the reduced competition. The company is not resting on its laurels; instead, it is aggressively expanding its services to new metropolitan areas known for their tech-savvy populations. Cities like Austin, Texas; Atlanta, Georgia; and Miami, Florida are on Waymo's expansion roadmap for 2026, leveraging partnerships such as the one with Uber to integrate robo-taxi services into popular ride-hailing platforms.

Notable Quote:
"Their partnership with Uber where they're going to be launching Waymo services on Uber's app..."
— Danny Lewis [03:27]

This strategic expansion aims to replicate Waymo's success in San Francisco, targeting regions with high concentrations of tech enthusiasts who are more likely to adopt and support autonomous transportation solutions.

Industry Insight:
Shweta Kajuriev from Wolf Research comments on Waymo's unparalleled position, stating, "There really isn't any other competitor in autonomous. What else are consumers today going to be dusting? There isn't anything else. And so that also allows Waymo the first mover advantage." [04:26]

c. Challenges Ahead for Waymo

Despite the promising outlook, Waymo faces several hurdles in its journey. The financial viability of operating driverless cars remains a concern, with higher operational costs compared to traditional ride-hailing services. These costs stem from advanced technology, sensors, and maintenance required for autonomous vehicles. Additionally, safety remains a paramount issue, as maintaining trust and avoiding accidents is crucial for widespread adoption.

Notable Quote:
"Waymo and a lot of these companies say that it's cheaper to operate because you're not paying a driver. But driverless cars have a lot of extra costs associated with them as well."
— Danny Lewis [04:46]

Analysts highlight that while Waymo enjoys a first-mover advantage, sustaining profitability and ensuring safety standards are critical for its long-term success.

3. The Next Frontier in AI: Long Thinking

Transitioning from autonomous vehicles, the episode shifts focus to artificial intelligence, specifically the concept of "long thinking." This advancement represents a significant leap in AI's problem-solving abilities, moving beyond rapid, surface-level responses to more deliberate and complex reasoning.

a. Understanding Long Thinking in AI

Bel Lin introduces the topic by comparing AI's current capabilities to human-like thinking systems. Stephen Rosenbush, WSJ’s Enterprise Technology Bureau Chief and columnist, elaborates on the distinction between "System One" and "System Two" thinking.

Notable Quote:
"System one is quick, instantaneous, doesn't have to work very hard. It's almost instinctive. And that's sort of where most generative AI is located right now."
— Steven Rosenbush [07:40]

System Two Thinking:
System Two involves more deliberate and effortful mental activities, akin to solving complex problems and making reasoned decisions. AI models incorporating long thinking can engage in deeper analysis, potentially reducing errors like hallucinations and improving performance in areas requiring intricate computations.

b. Benefits of Long Thinking AI Models

Long thinking AI models promise significant enhancements in various fields. By allocating more time and computational resources, these models can tackle intricate scientific, mathematical, and coding challenges more effectively. This capability leads to more accurate and reliable outcomes, fostering advancements in areas such as personalized medicine and global weather prediction.

Notable Quote:
"The O1 models have the capacity to step back and say, maybe this isn't the best approach. Let me try another approach to solve the problem."
— Steven Rosenbush [10:36]

This self-critical element of long thinking AI allows models to iterate on solutions, thereby minimizing mistakes and improving overall accuracy.

c. The Path Toward Artificial General Intelligence (AGI)

The conversation also touches upon the broader implications of long thinking AI in the pursuit of Artificial General Intelligence (AGI). While AGI remains a theoretical construct, advancements in long thinking represent incremental steps towards more generalized and human-like reasoning abilities in machines.

Notable Quote:
"The agents are in turn a step along the path toward some sort of AGI or think human, like broad based reasoning."
— Steven Rosenbush [09:00]

d. Potential Concerns and Ethical Considerations

Despite the promising developments, long thinking AI introduces new challenges. Ethical considerations regarding the deployment and oversight of such powerful technologies are paramount. Ensuring that AI is used responsibly to solve societal problems without creating new ones requires robust governance and clear guidelines.

Notable Quote:
"There’s a need to think about how the technology is put to use, what guardrails are in place."
— Steven Rosenbush [12:08]

4. Conclusion

The WSJ Tech News Briefing episode "Why AI’s Next Leap Forward Is ‘Long Thinking’" offers a comprehensive exploration of two transformative areas in technology today. Waymo's strengthened position in the autonomous vehicle market underscores the dynamic and competitive nature of tech industries, while advancements in AI's long thinking capabilities herald a new era of intelligent problem-solving. As these technologies evolve, their implications for society, ethics, and future innovations will continue to shape the technological landscape.
