Why You Should Wait Out AI’s Super-Spending False Start

About this episode

Merryn Somerset Webb discusses AI hype and reality with Janusz Marecki, focusing on the limitations of large language models.

Merryn Somerset Webb sits down with Janusz Marecki, CEO & Founder of Fractal Brain and AI Partner at Ahren Innovation Capital, for an insider perspective on AI hype vs. reality—and what may come next. The focus is on large language models (LLMs)—and whether they are hitting fundamental limits. Marecki discusses the data ceiling (we’ve used most high-quality internet data), diminishing returns from scaling compute and persistent issues like hallucinations and probabilistic errors.
