Contrary to the post-COVID trend of tech decentralization, the intense talent and capital requirements of AI have caused a rapid re-centralization. Silicon Valley has 'snapped back' into a hyper-concentrated hub, with nearly all significant Western AI companies originating within a small geographic radius.

Today's market is more fragile than during the dot-com bubble because value is even more concentrated in a few tech giants. Ten companies now represent 40% of the S&P 500. This hyper-concentration means the failure of a single company or trend (like AI) doesn't just impact a sector; it threatens the entire global economy, removing all robustness from the system.

The SVB crisis wasn't a traditional bank run caused by bad loans. It was the first instance where the speed of the internet and digital fund transfers outpaced regulatory reaction, turning a manageable asset-liability mismatch into a systemic crisis. This highlights a new type of technological 'tail risk' for modern banking.

Silicon Valley Bank was already a member of deposit networks that could have prevented its collapse. However, 94% of its deposits remained uninsured because the bank failed to actually use the tools at its disposal. This reveals that the mere existence of a solution is worthless without proper implementation, integration, and incentives for adoption within an organization.

In the hybrid capital market, the ability to deploy capital at scale is a significant competitive advantage. While many firms can handle smaller $20-40 million deals, very few can quickly underwrite and commit to a $500+ million transaction. This scarcity of scaled players creates a less competitive, inefficient market for those who can operate at that level.

America's system of nearly 10,000 banks is not a market inefficiency but a direct result of the founding fathers' aversion to centralized, oligopolistic British banks. They deliberately architected a fractured system to prevent the concentration of financial power and to better serve local business people, a principle that still shapes the economy today.

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.

Large platforms focus on massive opportunities right in front of them ('gold bricks at their feet'). They consciously ignore even valuable markets that require more effort ('gold bricks 100 feet away'). This strategic neglect creates defensible spaces for startups in those niche areas.

The global economy's reliance on a few dominant tech companies creates systemic risk. Unlike a robust, diversified economy, a downturn in a single key player like NVIDIA could trigger a disproportionately severe global recession, described as 'stage four walking pneumonia.' This concentration makes the entire system fragile.
