Micron is set to invest $9.6 billion in a new high-bandwidth memory (HBM) facility in Japan, with construction starting in May 2022 and shipments expected by 2028. The Japanese government may provide up to 500 billion yen in subsidies for the project. This move comes as HBM becomes a critical component in the AI supply chain, with Micron aiming to increase its market share through strategic partnerships with Nvidia and AMD. The expansion aligns with the industry's shift towards next-generation AI accelerators requiring advanced memory technologies. Japan's efforts to attract foreign chipmakers, like Micron, are part of a broader strategy to enhance domestic semiconductor capabilities.

Talent over tokens: AI models are becoming more expensive to run, and productivity gains are limited — efficient workers might be the solution to strained budgets

As AI models become more expensive to run, with costs exceeding those of actual workers, companies are facing strained budgets. Despite the promise of productivity gains through AI deployment, many firms are not seeing the expected returns. High costs associated with AI usage are leading to budget exhaustion, with examples like Uber spending its annual AI budget in a few weeks. As AI spending continues to rise, companies may need to reconsider their reliance on AI and potentially invest in efficient human workers instead.
