The success of personal AI assistants signals a massive shift in compute usage. While training models is resource-intensive, the next 10x in demand will come from widespread, continuous inference as millions of users run these agents. This effectively means consumers are buying fractions of datacenter GPUs like the GB200.

Unlike simple classification (one pass), generative AI performs recursive inference. Each new token (word, pixel) requires a full pass through the model, turning a single prompt into a series of demanding computations. This makes inference a major, ongoing driver of GPU demand, rivaling training.
The frenzy over Mac Minis to run Moltbot is a "sideshow." The true economic impact is the massive increase in GPU/TPU demand for inference. Each user running a persistent personal agent is effectively consuming the output of a dedicated data center chip, not just a local machine.
The vast network of consumer devices represents a massive, underutilized compute resource. Companies like Apple and Tesla can leverage these devices for AI workloads when they're idle, creating a virtual cloud where users have already paid for the hardware (CapEx).
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.
The current focus on building massive, centralized AI training clusters represents the 'mainframe' era of AI. The next three years will see a shift toward a distributed model, similar to computing's move from mainframes to PCs. This involves pushing smaller, efficient inference models out to a wide array of devices.
The next major hardware cycle will be driven by user demand for local AI models that run on personal machines, ensuring privacy and control away from corporate or government surveillance. This shift from a purely cloud-centric paradigm will spark massive demand for more powerful personal computers and laptops.
AI's computational needs are not just from initial training. They compound exponentially due to post-training (reinforcement learning) and inference (multi-step reasoning), creating a much larger demand profile than previously understood and driving a billion-X increase in compute.
CoreWeave, a major AI infrastructure provider, reports its compute workload is shifting from two-thirds training to nearly 50% inference. This indicates the AI industry is moving beyond model creation to real-world application and monetization, a crucial sign of enterprise adoption and market maturity.
While the most powerful AI will reside in large "god models" (like supercomputers), the majority of the market volume will come from smaller, specialized models. These will cascade down in size and cost, eventually being embedded in every device, much like microchips proliferated from mainframes.
The narrative of endless demand for NVIDIA's high-end GPUs is flawed. It will be cracked by two forces: the shift of AI inference to on-device flash memory, reducing cloud reliance, and Google's ability to give away its increasingly powerful Gemini AI for free, undercutting the revenue models that fuel GPU demand.
