Global tech rout deepens after US earnings stoke AI spending fears

A global tech rout has deepened as US earnings reports trigger significant fears regarding AI spending. Big Tech companies, including Google, Amazon and Meta, have seen nearly $900bn in value erased due to soaring cash burn. This trend has led Wall Street to question the actual price of the AI boom. Consequently, Japan's tech-heavy Nikkei 225 index has declined, and Wall Street is expected to open lower as investors react to these financial pressures.
