After a decade of abundant "growth capex" building new infrastructure, the economic pendulum is swinging towards "maintenance capex." This creates a massive, overlooked opportunity for technologies that service existing assets, like predictive software, acoustic sensors, and remote repair robots.

Successful "American Dynamism" companies de-risk hardware development by initially using off-the-shelf commodity components. Their unique value comes from pairing this accessible hardware with sophisticated, proprietary software for AI, computer vision, and autonomy. This approach lowers capital intensity and accelerates time-to-market compared to traditional hardware manufacturing.

Instead of selling software to traditional industries, a more defensible approach is to build vertically integrated companies. This involves acquiring or starting a business in a non-sexy industry (e.g., a law firm, hospital) and rebuilding its entire operational stack with AI at its core, something a pure software vendor cannot do.

Despite bubble fears, Nvidia’s record earnings signal a virtuous cycle. The real long-term growth is not just from model training but from the coming explosion in inference demand required for AI agents, robotics, and multimodal AI integrated into every device and application.

Most companies use AI for optimization—making existing processes faster and cheaper. The greater opportunity is innovation: using AI to create entirely new forms of value. This "10x thinking" is critical for growth, especially as pure efficiency gains will ultimately lead to a reduced need for human workers.

Scientific research is being transformed from a physical to a digital process. Like musicians using GarageBand, scientists will soon use cloud platforms to command remote robotic labs to run experiments. This decouples the scientist from the physical bench, turning a capital expense into a recurring operational expense.

While consumer fintech gets the hype, the most systematically important opportunities lie in building 'utility services' that connect existing institutions. These complex, non-sexy infrastructure plays—like deposit networks—enable the entire ecosystem to function more efficiently, creating a deep moat by becoming critical financial market plumbing.

Historically, labor costs dwarfed software spending. As AI automates tasks, software budgets will balloon, turning into a primary corporate expense. This forces CFOs to scrutinize software ROI with the same rigor they once applied only to their workforce.

Unlike SaaS startups focused on finding product-market fit (market risk), deep tech ventures tackle immense technical challenges. If they succeed, they enter massive, pre-existing trillion-dollar markets like energy or shipping where demand is virtually guaranteed, eliminating market risk entirely.

Instead of predicting short-term outcomes, focus on macro trends that seem inevitable over a decade (e.g., more e-commerce, more 3D interaction). This framework, used by Tim Ferriss to invest in Shopify and by Roblox for mobile, helps identify high-potential areas and build with conviction.

Unlike traditional software that supports workflows, AI can execute them. This shifts the value proposition from optimizing IT budgets to replacing entire labor functions, massively expanding the total addressable market for software companies.
