Waymo Halts Operations in Four Cities Amid Heavy Rain; Deployment Speed vs. Safety Dilemma
- Waymo's robotaxi service was temporarily suspended in four cities after repeatedly entering flooded areas.
- Deploying to the real world first and fixing exceptions later only works if the product can safely stop upon failure.
- If edge cases keep emerging only after deployment, the critical factor for competitors entering later is not speed but how early they embed stopping conditions into their products.
- According to Ars Technica, the U.S. government is investing a total of $2 billion in equity, not grants, across nine quantum computing companies.
- The initial beneficiaries are government-selected firms, but for adjacent sector founders, this choice significantly boosts customer trust and private follow-on investments.
- However, as government funding increases, conditions on technology usage and information disclosure may apply, so it is advisable to review the rights attached to the funding before focusing on the amount.
Reid Hoffman × Siddhartha Mukherjee, AI Cancer Research Startup Manas AI Raises $24.6 Million
- Manas AI, co-founded by Reid Hoffman and oncologist Siddhartha Mukherjee, raised $24.6 million in seed funding.
- The combination of a platform entrepreneur and a cancer researcher likely moved investors quickly.
- However, there is still no public pipeline.

KVBoost: Reducing LLM First Token Delay by 5–48× via KV Cache Reuse, Works Without GPU
- The open-source KVBoost was posted on Hacker News.
- It splits input into chunks, hashes them, and reuses the KV cache directly when the same chunk reoccurs.
- It reduced time to first token by 5–48 times and runs on top of HuggingFace generate() without requiring infrastructure changes.
- Before adopting it, we need to check how often the same context actually repeats in our requests to make these numbers meaningful.
What Hyundai's HTWO Showed in Rotterdam: A Gateway for Korean Hydrogen Startups to Go Global
- Hyundai Motor Group participated in the World Hydrogen Summit in Rotterdam with an exclusive Korean pavilion booth, unveiling the next-generation Nexo and the HTWO fuel cell system together.
- With about 10,000 attendees from over 100 countries, it was the perfect stage to promote the Nexo, which had just started sales in Europe.
- Hydrogen startups should focus on developing capabilities such as parts, operational software, and certifications that local buyers can independently purchase, rather than relying solely on the halo effect of complete vehicles.
