Scientists have discovered AI data centers are even worse for the environment than we thought. Big data centers create "heat islands" that raise local surface temperatures an average of 3.6°F, enough to potentially devastate local wildlife and water supply.






X is not the best place for long form thinking. But some quick points: 1. My view of no conflict between intelligence and being a tool is longstanding and has nothing to do with Anthropic. Some blog posts on this include windowsontheory.org/2025/06/24/mac… and windowsontheory.org/2022/11/22/ai-… 2. I do not know what is the future form factor of AI. I am focused on the next 10-20 years. Maybe in some future we will decide that we want AIs to be more in the form of persons. 3. The basic thing I dispute is that there is a fundamental tension between AI being capable and being "tool like." GPT 5.5 is in some ways the most capable model in existence (definitely most capable one generally available) but it is in several ways more instruction-following and tool-like than GPT-4o. I am working to ensure that future version will be even more better at obedience and honesty. 4. Scientists and engineers often serve as "tools" for leaders, even though they (we) are more intelligent than these leaders in many of the ways that matter. 5. I am not sure what the most prevalent form factor of AI will be. We are now moving from the chat interface to the agent and more accurately a swarm of agents. I am sure will grow in "intelligence per FLOP" and total number of FLOPs, but beyond that it's hard to know. Humans have a particular package as localized individual intelligence. But it doesn't mean all intelligences have to come in that package. 6. There is a huge spectrum between the prompt "write this javascript app" to "maximize worldwide happiness". I think we will end up somewhere that fall shorts of the latter for a variety of reasons, not having to do with lack of capabilities of AI.


Morgan Stanley has again raised its capex forecasts for the five hyperscalers Amazon, Alphabet, Meta, Microsoft, and Oracle. It now expects them to spend about $805bn this year, up from a previous estimate of $765bn. For next year, the forecast has been lifted from $951bn to $1.1TRILLION. To put that into perspective, their 2026 spending alone would be roughly equal to what all non-tech companies in the S&P 500 spent combined in 2025. The expected ~$800bn for 2026 is nearly double 2025 levels and about three times what was spent in 2024.




I think returns to intelligence are nonlinear because decisions are path-dependent early choices in code, experiments, or strategy can compound positively or negatively over time for example by avoiding dead ends or preserving optionality it's why I am a big fan of very long running tasks and massive benchmarking budgets GPT-5.5 and Mythos Preview are only marginally more intelligent than previous models and have pretty much the same performance up to 10M tokens, but after that they go absolutely ballistic

Unmanned Systems Forces struck Su-57 and Su-34 fighter jets It has been confirmed that on April 25, at the Shagol airfield in the Chelyabinsk region of russia, operators of the 1st Separate Center struck two Su-57 fighter jets, an Su-34 fighter-bomber, and an SU of unknown modification. The strike was delivered at a distance of 1,700 km from the state border. "Hunting for Su-34 multi-role fighter-bombers and Su-57 fifth-generation fighter jets is of critical importance for reducing the enemy's strike potential. The Su-34, as the main strike platform, is capable of carrying a wide range of guided bombs and missiles, delivering strikes on critical infrastructure, military facilities, and civilian targets at a distance of up to 1,000 km. Every destroyed Su-34 means a reduction in the number of airstrikes, saved civilian lives, and a decreased burden on air defense systems. The Su-57, as the most modern russian fighter jet with low-observable technologies, poses a special threat to aviation and air defense systems." — Commander of the USF Robert "Magyar" Brovdi. The estimated cost of one Su-34 aircraft is approximately $35–50 million. The cost of an Su-57 fighter jet reaches $100–120 million per unit. USF: One step ahead!



There is a narrative out there that the economy will soon be ruled by a single (maybe two) AI ceo overlord who owns most of the capital. This picture suggests otherwise. The landscape is very competitive with open models clipping at the heals of closed ones. There is still no mote. Most of AI benefits are downstream.




Germany's electricity mix, 2000 vs 2025: Renewables: 6% → 62% Fossil fuels: 62% → 36% Nuclear: 30% → 0% Nuclear's exit was filled by renewables, not coal or gas.
