- •How this changes investment priorities
- •Where AI investment has highest returns
- •Building an economics-based framework
The Cost Curve Collapse
The marginal cost of intelligence has followed the same trajectory as computing, communication, and storage: exponential decline. What cost $100 in 2020 costs $0.50 in 2025. This collapse changes the economics of everything that involves intelligence: analysis, decision-making, prediction, explanation. Tasks that were economically infeasible are now trivial.
This is not incremental improvement—it is categorical change. Intelligence that was too expensive to apply at scale is now trivially cheap. The constraints that shaped strategy have shifted fundamentally. What was impossible is now possible. What was expensive is now cheap. What was worth optimizing is now worth doing at scale.
The implications are profound. Tasks that relied on sampling because processing was expensive can now process full populations. Decisions that relied on rules because reasoning was expensive can now use actual intelligence. Analysis that required experts because understanding was expensive can now be automated. The economics have changed; the strategy must change with them.
The question is not whether to invest in AI. The answer is obviously yes. The question is where the return is highest—which applications will generate the most value relative to investment. Answering this question requires understanding the economics of intelligence.
The Economic Shift
Intelligence costs have dropped from $100 to $0.50 per million tokens since 2020. What was too expensive is now trivial. The question is not whether to invest, but where return is highest.
Investment Priorities
Where should you invest? The answer comes from understanding where intelligence was previously too expensive and is now cheap—that is where the largest economic shifts occur.
Start with high-volume, repetitive decisions. Every decision that humans make repeatedly is a candidate for AI. The value scales with volume. A decision made 100,000 times per year creates more value than one made 100 times, even if each decision has similar complexity.
Move to complex decisions where AI can process more information than humans can. Some decisions require considering more variables than humans can hold in memory. AI excels at these—more context, more factors, more analysis than any human could manage.
Target areas where current approaches rely on sampling or rules. The old approaches were compromises born of necessity. Now that intelligence is cheap, these compromises are unnecessary. Replace sampling with full population analysis. Replace rules with reasoning.
Prioritize applications where the cost of errors is manageable while the value of improvement is high. Not every application has equal economics. Find the places where AI can create the most value relative to risk.
The best investments are often not the most obvious. Look for places where intelligence was previously too expensive to apply. That is where the largest economic shifts occur.
Building the Framework
Developing an economics-based framework for AI investment requires understanding both the technology and the business case. Several principles guide this analysis.
Quantify the value of improvement. For each potential application, estimate: how much does the current process cost, how much could AI improve it, what is the value of that improvement? Focus on applications where value is high.
Assess implementation cost. Building AI capabilities requires investment: technology, talent, integration, change management. Estimate these costs realistically. The best opportunities are those with high value and reasonable cost.
Consider the competition. If competitors have already invested heavily, the returns may be lower. Look for applications where you can build advantages, not just catch up.
Build the foundation. Some investments create value across multiple applications. Data infrastructure, talent development, organizational capabilities—these are worth investing in even if specific applications have uncertain returns.
The framework should be revisited regularly. The economics of AI are changing rapidly. What is true today may not be true tomorrow. Keep the framework current.
