At my job on the compute policy team at IAPS, we recently started a Substack that we call The Substrate. I think this could be of interest to some here, since I quite often see discussions on LessWrong around export controls, hardware-enabled mechanisms, security, and other compute-governance-related topics.

Here are the posts we've published so far:

• For chip exports, quantity is at least as important as quality, about how to best set AI chip export policy
• The case for paying whistleblowers to report on export violations, about the Stop Stealing Our Chips Act
• BIS is getting more funding—here's how to spend it, about the upcoming Bureau of Industry and Security budget increase, and what BIS plans to and should do with the money
• Why securing AI model weights isn’t enough, about AI integrity (that is, ensuring AI models don't have backdoors, etc.)

To make this quick take not merely an advertisement, I would also be happy to discuss anything about any of these posts, and/or to hear suggestions for things that we should write about.
