Changes in Capex Intensity Matter More than Intensity Itself

Lots of industries are capital intensive, and one might argue such industries tend to be slower growing, such as carbon-based energy; utilities of all types and telecommunications. So it is almost pointless to complain about high levels of capex in such industries. 


Industry

Sample Public Company

Annual Capex as % of Revenue

Oil & Gas

Exxon Mobil (XOM)

15-25%

Utilities

NextEra Energy (NEE)

15-25%

Telecommunications

Verizon Communications (VZ)

15-25%

Semiconductors

Intel Corporation (INTC)

15-25%

Automotive

Ford Motor Company (F)

10-15%


More-relevant questions might be raised about increasing levels of investment, not necessarily high levels of investment that are steady. And that clearly is the case for hyperscale cloud computing “as a service” providers.

Other industries feature lower levels of annual capital investment intensity, but might see capex increases to support AI operations, including software.

Why One-Bit LLMs Matter

Though much of the investor concern about high levels of infrastructure investment to support generative artificial intelligence, it might be easy to miss simultaneous moves to create lower-computational cost implementations, such as small language models.


It might seem incongruous to talk about “one-bit large language models,” since the whole point of such models is to reduce computational intensity and cost: they might not be “large,” in other words, or if based on LLMs, execute on limited-resource platforms (thus saving energy, computational resources and cost). 


For example, some point to the power consumption advantages of one-bit models, compared to LLMs of any size. Some argue BitNet might have an order of magnitude more efficiency in that regard.

Edge computing and internet of things use cases (sensors, for example), might use one-bit LLMs profitably on edge devices for tasks such as simple anomaly detection, sensor data analysis, and local decision-making.


Such real-time monitoring and analysis of environmental conditions, equipment performance, or security threats, with minimal latency, often do not require the full use of LLMs and infrastructure. 

.

For similar reasons, mobile applications running directly onboard edge devices (smartphones, for example), can support real-time translation, voice assistants, and text analysis without relying on remote resources.


Some augmented reality use cases could support real-time object recognition and information overlays while conserving battery life.


The point is that AI inference operations do not all require the cost, energy consumption or computational precision of full frontier AI models to produce value. 


Smaller models seemingly could be used in financial analysis operations for trend analysis or fraud detection without the full overhead of LLMs.


In industrial settings, much predictive maintenance value could be wrung from simple, lighter-weight models. 


The point is that lots of useful inference use cases might be possible without the speed or accuracy advantages of bigger LLMs.

The Roots of our Discontent

Political disagreements these days seem particularly intractable for all sorts of reasons, but among them are radically conflicting ideas about the possibility of truth; application of reason and existence of universal truth. 


For example, we might differ on whether history or human experience can be known in a universal way, or whether only particularisms matter. .


That, in turn, is a difference of opinion about whether “nature” is subjective or objective.  Some consider "truth" to be shaped by language, culture, and power structures, leading to a variety of perspectives, all equally valid. Others essentially argue that objective and universal truths do exist, independent of our personal beliefs. 


Postmodernists argue that language shapes our understanding of reality, hence the importance of words and “names.


Likewise, some might contend that objectivity is an illusion. Others argue objectivity is necessary and obtainable to a substantial degree. Adherents of the former tend to believe that all knowledge is influenced by personal, cultural, and historical contexts. Those who take the latter view believe there is a difference between shared “reality” and individual beliefs. 


Some value diversity, plurality, and the coexistence of multiple viewpoints above shared common values, unity the necessity of choice among competing ideas. 


In other words, many embrace “Postmodernism” while others operate within the intellectual context of the Enlightenment. 


The rancor, hatred, bad manners and absolutism we often see in politics is rooted in fundamentally different universes of thought.

Net AI Sustainability Footprint Might be Lower, Even if Data Center Footprint is Higher

Nobody knows yet whether higher energy consumption to support artificial intelligence compute operations will ultimately be offset by lower consumption by industries, firms and consumers that use AI to manage their energy footprints


But it seems inevitable that AI operations are going to contribute to a significant boost in data center energy requirements

Still, some researchers expect net gains in energy efficiency and potential greenhouse gas emissions as AI is applied to industries.

AI increases energy use, but optimizing energy systems with AI can lead to net emissions reduction. The carbon footprint varies depending on electricity sources.

Will AI Accelerate or Delay the Race to Net-Zero Emissions?

2023

Nature

AI applications in sectors like transportation and energy can reduce global emissions by up to 10%, but data centers' energy use may offset gains if unchecked.

Potential of AI in Reducing Energy and Carbon Emissions

2022

Nature

AI can lower global energy consumption by up to 19% by 2050 through efficiency improvements but needs sustainable practices for data center energy use.

Tackling AI’s Climate Change Problem

2023

MIT Sloan Review

Large AI models contribute significantly to emissions; however, AI-driven optimizations can reduce industrial and operational carbon footprints.

Reduce Carbon and Costs with the Power of AI

2023

BCG

AI helps companies track and reduce emissions, potentially cutting global GHG emissions by 5.3 gigatons by 2030 while improving efficiency.


The point is that it is hard to say whether net increases or decreases in carbon or other footprint will result from wide scale AI usage. More computation means more energy consumption, which increases data center emissions footprint. 


But AI should ultimately enable lower energy consumption by a wide range of industries.
