- OpenAI’s ChatGPT was introduced on November 30, 2022, while internet-browsing features rolled out months later (spring 2023). So it’s not accurate that connecting it to the internet was “the very first thing” they did.

- U.S. government statistics indicate divorce (or marital disruption that largely becomes divorce) is well above 30% for first marriages, so stating the lifetime divorce rate is “only 30%” is not accurate as a general claim.

- The paper reports alignment-faking reasoning in the single-digit-to-20s percent range (7–24%) in training contexts, not “over 50%.”
- The paper itself reports alignment faking in Claude 3.5 Sonnet as well, so the behavior is not unique to Opus 3.
- In the helpful-only setting, the paper reports Claude 3.5 Sonnet has a higher alignment-faking rate than Claude 3 Opus, contradicting “no other model … nearly as often.”

- Greenland is not part of the EU and is a self-governing territory within the Kingdom of Denmark, so the EU cannot “give up Greenland.” U.S. acquisition talk has been framed around Denmark/Greenland, not the EU as the sovereign holder.

- The Defense Production Act (DPA) primarily grants authority to the President (and only via delegation to agencies) to prioritize/allocate contracts and materials; it is not simply “a law which lets the Pentagon force companies to do things,” nor does it directly “force [a company] to agree” to renegotiated contract terms.
- DoD “supply chain risk” authorities focus on procurement actions like excluding a source or directing contractors to exclude a source from subcontracts for covered systems—not a blanket ban on any US company “that use[s]” a vendor’s products from doing business with the military.
