WILL DATA CENTERS CRASH THE ECONOMY?

Big Tech's $102.5 billion quarterly AI spending now exceeds dot-com era investment as a share of GDP, but the real risk lies in financing through "private credit" funds that operate outside traditional banking oversight. Banks have increased their exposure to these shadow lenders 14x since 2013, creating conditions where a synchronized AI market downturn could trigger defaults on data centers, cascading through private credit funds to their bank and insurance company lenders.

TOKENS ARE GETTING MORE EXPENSIVE

Models will always be cheaper next year, but users will expect more of them. The goalpost is always moving ahead. Even Anthropic, which has the most vertically integrated application layer on the planet, can't make a flat subscription with unlimited usage work. Companies without a plan are headed to the graveyard fast, as there are no investors writing checks for negative margin businesses. There's no figuring it out later when your AWS bill is larger than your revenue.

DOES THE BITTER LESSON HAVE LIMITS?

General methods that leverage computation are ultimately the most effective by a large margin. The eventual success of approaches based on scaling computation is often tinged with bitterness because it is success over a favored, human-centric approach. Developers need to be aware that their work might be overtaken by compute, but this shouldn't stop them from applying custom, human-crafted logic to get the job done.

PERSONA VECTORS: MONITORING AND CONTROLLING CHARACTER TRAITS IN LANGUAGE MODELS

Researchers extracted "persona vectors" by comparing neural network activity when models exhibit specific traits versus when they don't, revealing that personality changes follow predictable mathematical patterns. This discovery enables a counterintuitive "vaccination" approach that purposefully steers models toward undesirable traits during training to compensate for their tendency to “overfit” to negative traits.

AI'S OVERLOOKED $97 BILLION CONTRIBUTION TO THE ECONOMY

The US economy grew at an annual rate of 3% in the second quarter. Americans enjoyed roughly $97 billion in consumer surplus (the difference between the maximum a consumer is willing to pay for a good or service and its actual price) from generative AI tools in 2024. Around 40% of US adults are regular users of generative AI. As more digital goods become available for free, measuring benefits as well as costs will become increasingly important.
