Japan's AI Boom Prompts Cautious Optimism in Business and Engineering

A recent Japanese book on generative AI explains how engineers can treat AI as a powerful assistant that can boost productivity up to tenfold, provided they maintain deep system knowledge and carefully manage prompting context. The author stresses that AI remains a subordinate tool; human managers must retain responsibility for decisions and guard against hallucinations.

A concurrent commentary notes that AI has become ubiquitous in Japan, with specialist books filling bookstores and companies pouring massive funds into AI projects. While firms such as Google and Tesla saw soaring cloud revenues, their stock prices fell as AI spending drove free‑cash‑flow deficits, whereas Apple’s more modest AI outlay kept its shares buoyant. Analysts warn that the current wave may soon plateau, slowing investment in data‑centers and power infrastructure, and that a second, consumer‑focused AI wave could follow after a period of adjustment.
