While focus is on massive supercomputers for training next-gen models, the real supply chain constraint will be 'inference' chips—the GPUs needed to run models for billions of users. As adoption goes mainstream, demand for everyday AI use will far outstrip the supply of available hardware.

While GPUs dominate AI hardware discussions, the proliferation of AI agents is causing a significant, often overlooked, CPU shortage. Agents rely on CPUs for web queries, data processing, and other tasks needed to feed GPUs, straining existing infrastructure and driving new demand for companies like Arm and Intel.

The AI revolution isn't just about software. For the first time in years, venture capital is flowing into hardware like specialized semis and even into energy generation, because power is the core bottleneck for all AI progress.

Eclipse Ventures founder Lior Susan shares a quote from Sam Altman that flips a long-held venture assumption on its head. The massive compute and talent costs for foundational AI models mean that software—specifically AI—has become more capital-intensive than traditional hardware businesses, altering investment theses.

Strategic investments in AI labs, like NVIDIA's in Thinking Machines, are increasingly structured as complex deals trading equity for access to cutting-edge chips. This blurs the line between traditional venture capital and resource allocation, making compute access a form of currency as valuable as cash for capital-intensive AI startups.

The focus in AI has evolved from rapid software capability gains to the physical constraints of its adoption. The demand for compute power is expected to significantly outstrip supply, making infrastructure—not algorithms—the defining bottleneck for future growth.

While model performance gains headlines, the true strategic priority and bottleneck for AI leaders is the 'main quest' of securing compute. This involves raising massive capital and striking huge deals for chips and infrastructure. The primary competitive vector has shifted to a capital war for capacity.

The focus on GPUs for AI overlooks a critical bottleneck: CPU shortages. AI agents require massive CPU power for non-GPU tasks like web queries and data prep. This demand is straining existing infrastructure and creating new market opportunities for CPU makers like ARM.

While AI dramatically lowers the capital needed to build software, it creates a new significant expense: compute costs. Venture capital remains essential, but its purpose has shifted from funding initial development to covering substantial cloud and AI service bills as companies scale.
