Aligning Incentive Structures to Mitigate AI Failure Risks
Focusing on whether AI is sentient distracts from the actual problem: human-run systems that lack clear accountability. Instead of worrying about science fiction scenarios, focus on the unglamorous work of aligning incentives and strengthening workflows. This approach helps prevent the common, mid-level failures that are far more likely to occur.

Why Static Cosmological Models Stagnate Fundamental Physics Research
When models fit your data too perfectly, they can hinder scientific progress by hiding how the system actually works. Stop viewing stable metrics as final answers. Instead, look closely at the odd inconsistencies in your data, as these often reveal the true dynamics of the system.
