Is Another AI Winter Coming?

2025-05-19

This article explores the current state of artificial intelligence, arguing that current expectations are overly optimistic. From the failed machine translation projects of the 1960s to the limitations of Large Language Models (LLMs) today, the author contends that while AI finds application in specific areas like medical image recognition, it remains far from a true 'thinking machine'. LLMs suffer from 'hallucinations,' frequently generating false information requiring extensive human fact-checking, a significant gap between reality and hype. Current AI applications in customer service and code assistance show promise but their profitability and broad applicability remain unproven. The author suggests that given the changing economic climate and inherent limitations of the technology, the AI field may face another 'winter'.

Trump, the Fed, and the Distorted Reality of ZIRP: The Hidden Economic Risks Behind the Stock Market's Euphoria

This article analyzes Trump's attempts to interfere with the Fed's independence and the distorting effects of the long-term zero interest rate policy (ZIRP) on the economy. Trump's attempt to fire a Fed governor is motivated by a desire to force interest rate cuts, threatening the Fed's independence and potentially leading to economic catastrophe. The article points out that ZIRP led to irrational expectations about future cash flows, fueling tech bubbles and financial risks. The stock market's optimistic response to Trump's actions contrasts sharply with the bond market's concerns about economic risks – a divergence that will eventually lead to market correction. The author argues that the Fed's independence is crucial and that the long-term effects of ZIRP represent a serious economic risk.

AI's Energy Hunger: Data Center Power Consumption to Double by 2030

A new report from the International Energy Agency (IEA) reveals that data center electricity consumption is projected to more than double by 2030, primarily driven by Artificial Intelligence (AI). The report forecasts data centers will consume 945 terawatt-hours (TWh) in 2030, roughly equivalent to Japan's current annual electricity consumption. AI servers already accounted for 15% of total data center energy demand in 2024. While developing economies are projected to account for only 5% of future growth, advanced economies will contribute over 20%. The IEA estimates that 20% of planned data centers might face grid connection delays.
