Alibaba’s Joe Tsai warns of potential AI data centre bubble
Alibaba Chairman Joe Tsai warned of a potential bubble in data centre construction, suggesting that the rapid pace of buildouts might exceed current demand for AI services, Bloomberg reported from the HSBC Global Investment Summit in Hong Kong earlier today. He criticised the indiscriminate rush by tech firms and investors to construct server bases without clear customer demand.Critics of the ongoing AI goldrush have pointed out the lack of real-world AI applications and the unsustainable spending by companies like Microsoft, Amazon, and Alphabet, who have pledged billions for AI infrastructure. Tsai raised concerns over data centre projects being funded without securing uptake agreements and cautioned that these investments are being made ahead of actual demand, potentially leading to a bubble.
PsiQuantum raising $750 million at $6 billion valuation
PsiQuantum, a quantum computing startup, is raising at least $750 million, led by BlackRock, at a $6 billion valuation, Reuters reported exclusively. The company, using existing photonics technology, aims to mass-produce quantum chips at GlobalFoundries" New York factory. Quantum computing promises to solve complex problems, potentially revolutionising fields like materials science and pharmaceuticals.Recently, major tech firms such as Google"s Alphabet, Microsoft, Amazon, and Nvidia, have made advancements in quantum computing. PsiQuantum is collaborating with the Australian and US governments to build quantum computers in Brisbane and Chicago, aiming for a useful machine by 2029 or sooner.

IIT-M researchers developing a zinc-air alternative to Li-ion
Researchers at IIT Madras are developing zinc-air batteries as a safer, cost-effective, and sustainable alternative to lithium-ion batteries, which are mostly imported, Economic Times reported. Zinc-air batteries offer numerous advantages, including safety, affordability, and higher energy density, making them suitable for India"s increasing demand for energy storage systems.The challenges include potential corrosion and sluggish kinetics, which require efficient catalysts for optimal performance. Companies like Salient Energy and Urban Electric Power are also working on zinc-based battery technologies for grid-scale applications. Professor Ranjit Bauri and research scholar Sai Vani Terlapu are leading the project at IIT-M.
