Two years ago we started building @Halcyon because we believed that modern AI could fundamentally change how the energy industry accesses and uses information ⚡️

Finally the voice of reason thank this @Plinz 🙏🏻
people are worried about how ai is using up all the water, but it’s actually the only way that we can stop sea level rise. also water is stored in the ai model only during training. when you use the model, the water is released again.

Signs you might be super jelly you didn't get to invest 👇
Signs you might be trying to get your frontier AI lab nationalized: You compare it to nukes… threaten half of white-collar jobs… warn recursive self-improvement could end humanity… then race ahead anyway. In other words, you want the government to save us from… you.

Up to $850 billion is being invested in U.S. power and digital infrastructure this year alone. State public utility commissions are generating more filings than ever. Every RTO/ISO, and federal energy agency is producing documents that matter. The information is all public. Almost none of it is manageable.
