Weekly Dose of Optimism #202
Brief
Packy McCormick's Weekly Dose of Optimism #202 (published 2026-07-17) collects a string of industrial, biomedical, robotics, and open-AI milestones. Saronic — an Austin autonomous shipbuilder — reportedly used three 24-foot Corsair drones in a combat strike near Bandar Abbas and announced Port Alpha, a $3+ billion Brownsville, TX shipyard: phase one covers 835 acres (expandable to ~4,400), construction slated to start in 2026, operations in 2028, initial capacity for ships up to 850 ft and a potential ~2 million gross tons/year at full build, creating up to 10,000 direct jobs over a decade. In Austin, Base Power began a 40-MW residential battery deployment with Austin Energy, while TerraFirma closed a $100M Series A to commercialize robotic construction systems with experienced industry backers. The robotics wave included Walden Robotics exiting stealth with $300M at a $1.1B valuation and production robots already in a Toyota factory; Sunday Robotics unveiled ACT-2 for Memo, claiming one-shot fine-tuning that generalizes zero-shot with 99% task success and proposing a 'Solve' metric for real-world adaptation cost. In biotech, the FDA approved Merck's Lipfendra — the first oral macrocyclic-peptide PCSK9 inhibitor — delivering ~56% LDL reduction vs placebo (59% in hereditary cases). On AI, Moonshot AI published Kimi K3 (2.8T params, 1M-token context, sparse MoE 16/896, Kimi Delta Attention and Attention Residuals) with weights due 2026-07-27, while Thinking Machines released Inkling (975B MoE, 41B active, Apache 2.0) to accelerate open-weight model innovation.
Why it matters
Saronic used three of its 24-foot Corsair autonomous boats in a combat strike at Bandar Abbas (reported week of 2026-07-17); the startup also announced a $3+ billion Port Alpha shipyard in Brownsville, TX — phase 1: 835 acres (expandable to ~4,400), construction starting 2026, operations planned 2028, initial yard builds ships up to 850 ft and could reach ~2 million gross tons annual capacity, with up to 10,000 direct jobs over the next decade.
Key details
- Base Power Company began serving homeowners inside Austin Energy territory under a 40-megawatt residential battery agreement (announced week of 2026-07-17); TerraFirma raised a $100M Kleiner Perkins-led Series A to build robotic construction systems with investors/co-founders including Matt Grimm, Chris Power, and Justin Lopas.
- Walden Robotics exited stealth with $300M seed funding at a $1.1B valuation (co-led by Deviation Capital and Toyota investors); spun out of Toyota Research Institute in Jan 2026 under CEO Russ Tedrake, its full-stack robots were already deployed in a North American Toyota factory within two months.
- Sunday Robotics previewed ACT-2 for its Memo home robot, claiming one-shot fine-tuning that generalizes zero-shot with a 99% success rate and introduced the 'Solve' framework to benchmark real-world adaptation and scope.
- Merck's Lipfendra received FDA approval (announced week of 2026-07-17) as the first oral PCSK9 inhibitor: once-daily macrocyclic peptide pill with placebo-adjusted LDL reductions ~56% (broad trial) and ~59% (familial hypercholesterolemia); priced ~ $10.50/day in the article.
- Open-weight model momentum: Moonshot AI released Kimi K3 (2.8T params, 1,000,000-token context, native vision; sparse MoE activating 16/896 experts) with Kimi Delta Attention (up to 6.3x faster decoding in long contexts) and Attention Residuals (~25% higher training efficiency); full weights scheduled for 2026-07-27. Thinking Machines released Inkling (975B param MoE, 41B active, 1M-token context) under Apache 2.0.
