💾 You're now able to persist your RootFS across reboots! Keep your root filesystem across restarts or even updates. Perfect for caches you don't want to rebuild. (You should probably still not use this for critical data, use volumes for that)

🧠 Building AI software? Your biggest risk isn't the code, it's trust calibration! When users over-trust your AI, disasters happen. When they under-trust, potential dies. The sweet spot? It's more nuanced than you think.

🤖 The future isn't model agnostic! Why specialized infrastructure beats one-size-fits-all approaches. Different AI models need different optimizations, from memory patterns to networking. Generic platforms create bottlenecks while specialized infra unlocks performance.
