Ben Evans' post "The Deep Research Problem" argues that while AI can impressively synthesize existing information and accelerate certain research tasks, it fundamentally lacks the capacity for original scientific discovery. AI excels at pattern recognition and prediction within established frameworks, but genuine breakthroughs require formulating new questions, designing experiments to test novel hypotheses, and interpreting results with creative insight – abilities that remain uniquely human. Evans highlights the crucial role of tacit knowledge, intuition, and the iterative, often messy process of scientific exploration, which are difficult to codify and therefore beyond the current capabilities of AI. He concludes that AI will be a powerful tool to augment researchers, but it's unlikely to replace the core human element of scientific advancement.
Benedict Evans's blog post, "The Deep Research Problem," delves into the escalating complexities and costs associated with semiconductor research and development, specifically focusing on the implications for advanced process nodes in chip manufacturing. Evans argues that the relentless pursuit of Moore's Law, which historically dictated the doubling of transistors on a chip every two years, is encountering significant economic and practical hurdles. He meticulously outlines how the sheer financial investment required for each new generation of process technology is dramatically increasing, reaching tens of billions of dollars per node. This exorbitant cost is driven by several factors, including the escalating complexity of design and manufacturing, the need for increasingly specialized and expensive equipment, and the diminishing returns on scaling as physical limitations become more pronounced.
The post emphasizes that this financial burden is becoming unsustainable for all but a select few, extraordinarily well-capitalized companies. Evans posits that only the largest players, such as TSMC, Samsung, and Intel, possess the necessary resources to remain competitive in this escalating arms race. This consolidation of power within a handful of industry giants raises concerns about potential limitations on innovation and market competition, as smaller players are effectively priced out of the cutting edge. The post also highlights the increasing specialization and technical expertise required to navigate these complex processes, further contributing to the barrier to entry for new competitors.
Evans further explores the implications of this trend for the broader technology landscape. He discusses how the rising cost of research and development might necessitate a shift in focus from pure performance gains to more nuanced improvements, such as power efficiency and specialized architectures. He suggests that the industry may be transitioning from an era of universal scaling to one of more tailored and application-specific advancements. The blog post concludes by highlighting the profound implications this shift will have on the semiconductor industry, predicting a potential bifurcation between a small number of companies capable of pursuing cutting-edge process nodes and a larger ecosystem focused on leveraging existing technologies for more specialized applications. This dynamic could reshape the competitive landscape and influence the direction of technological innovation in the years to come. The overall tone of the post is one of cautious observation, recognizing the historical significance of Moore's Law while acknowledging the formidable economic and technological challenges that are reshaping the future of semiconductor development.

HN commenters generally agree with Evans' premise that large language models (LLMs) struggle with deep research, especially in scientific domains. Several point out that LLMs excel at synthesizing existing knowledge and generating plausible-sounding text, but lack the ability to formulate novel hypotheses, design experiments, or critically evaluate evidence. Some suggest that LLMs could be valuable tools for researchers, helping with literature reviews or generating code, but won't replace the core skills of scientific inquiry. One commenter highlights the importance of "negative results" in research, something LLMs are ill-equipped to handle since they are trained on successful outcomes. Others discuss the limitations of current benchmarks for evaluating LLMs, arguing that they don't adequately capture the complexities of deep research. The potential for LLMs to accelerate "shallow" research and exacerbate the "publish or perish" problem is also raised. Finally, several commenters express skepticism about the feasibility of artificial general intelligence (AGI) altogether, suggesting that the limitations of LLMs in deep research reflect fundamental differences between human and machine cognition.
The Hacker News post titled "The Deep Research problem" (linking to a Ben Evans article of the same name) has generated a moderate discussion with several insightful comments. The central theme of the comments revolves around the increasing difficulty and cost of performing deep research, particularly in semiconductor manufacturing, and its implications for future innovation.
Several commenters agree with Evans' central premise. One commenter highlights the rising capital expenditures (CAPEX) in semiconductor fabrication, specifically mentioning TSMC's recent fab in Arizona projected to cost $40 billion. They link this escalating cost to the immense complexity of advanced nodes and the diminishing returns on investment, making it increasingly challenging for smaller players to compete. This reinforces Evans' point about the consolidation of research efforts within a handful of giant companies.
Another commenter expands on this by drawing parallels to the aerospace industry, where similar consolidation has occurred due to the massive research and development costs involved. They argue that this trend is natural in industries with high barriers to entry and suggest that we might see a similar pattern emerge in other deep tech sectors.
A different perspective is offered by a commenter who points out that while research might be consolidating in some areas, it's simultaneously exploding in others, particularly in software and AI. They contend that the barriers to entry in these fields are significantly lower, enabling smaller companies and even individuals to make significant contributions. This suggests a nuanced picture where deep research is becoming more concentrated in hardware-centric industries while remaining more distributed in software-driven fields.
Another commenter raises the point that the sheer volume of information necessary for deep research is growing exponentially, requiring increasingly specialized expertise. They suggest that this complexity necessitates larger teams and more sophisticated tools, further contributing to the rising costs and the trend toward consolidation.
One commenter questions the long-term implications of this trend, expressing concern about potential stagnation if innovation becomes confined to a few large entities. They suggest the need for alternative models of funding and collaboration to ensure continued progress in critical areas.
Finally, a comment highlights the increasing importance of software in even traditionally hardware-driven fields like semiconductors. They argue that as complexity increases, software becomes crucial for design, simulation, and optimization, potentially offering new avenues for innovation and perhaps even mitigating some of the escalating costs associated with hardware research.
Overall, the comments on Hacker News reflect a general agreement with Evans' observations about the growing challenges of deep research. They explore the various facets of this issue, from rising costs and consolidation to the shifting landscape of innovation and the increasing importance of software. The discussion highlights the complex and multifaceted nature of the problem and the need for further exploration and potential solutions.
