AI – Bubble or One of History's Most Productive Gold Rushes?
In this guest article, Gunnar Miller, Senior Advisor at investment boutique TEQ Capital, analyzes whether the current AI boom constitutes a bubble. He compares today's fundamentals with past technology bubbles, noting that the 'Magnificent Seven' trade at a P/E of about 33 and the S&P 500's Shiller P/E of 40 parallels dot-com levels. Tech companies are projected to invest $400 billion in AI infrastructure this year, surpassing the inflation-adjusted cost of the Apollo program. Miller warns against 'ChatGDP' — circular deals among AI players like OpenAI, which has announced over $800 billion in investments and partnerships, potentially inflating perceived dynamism. He advises investors to finance the buildout rather than fear a bubble, while acknowledging risks of overcapacity and long recovery timelines.

Fired OpenAI Researchers Dispute Misconduct Claims, Warn of Chilling Effect
Three OpenAI safety researchers, Jasmine Wang, Tomek Korbak, and Mikita Balesni, who were fired last week, have published an open letter denying allegations of mishandling sensitive information. They warn that their dismissal creates a chilling effect that stifles AI safety work and open dialogue within the company. The researchers say they acted in good faith and within company norms, and that the reasons for their firing are unclear. They urge OpenAI to uphold its commitments to third-party safety auditors and maintain a transparent culture. OpenAI responded with an internal memo denying retaliation and stating that employees are not terminated for raising concerns, but did not address specific policy violations or circumstances of the dismissal. The dispute highlights tensions between internal safety research and company communication policies at a time when OpenAI faces scrutiny over safety incidents.
