IBM's mainframe sales falter as AI disrupts legacy software; OpenAI explores hardware

IBM experienced its worst single-day stock drop in 115 years, signaling a potential end to the mainframe era that defined enterprise IT for decades. The company's mainframe sales and associated software are faltering, with management pointing to AI spending as the cause. According to Ben Thompson's analysis, however, the real threat is AI's ability to port essential backend programs off legacy mainframe technology—meaning those lost sales may never return. This represents a fundamental shift as AI makes migrating from archaic, expensive mainframes cheaper and easier than ever before.

On the OpenAI front, the company continues its summer of drama. It recently updated its ChatGPT Mac app, signaling priorities around a super-app strategy rather than pure chat. More intriguingly, reports emerged of OpenAI's first hardware product: an ambient speaker with robotic components. Andrew Sharp and Ben Thompson discussed why this experiment makes sense as a low-risk entry into hardware. Separately, Apple's trade secrets lawsuit against OpenAI appears to be more smoke than fire, involving one former employee. OpenAI also faces questions about whether it's abandoning the chat category it pioneered as it refashions Codex into ChatGPT.
