A recent breakthrough from AI startup Subquadratic suggests they’ve solved a long-standing mathematical bottleneck in large language models (LLMs), making these models faster, cheaper and more energy-efficient. However, many experts remain skeptical, suggesting that while the approach is worth observing, it may not be as revolutionary as claimed.

Brain-computer interfaces (BCIs) are also making significant strides, with China being the first country to approve a BCI for medical use. ALS patient Casey Harrell, who is the first power user of such technology, has regained his ability to maintain income and communicate with loved ones, marking a step towards more advanced, market-ready BCIs.
