5. Disrupting a new covert influence campaign from Russia
Anthropic has disrupted a covert influence campaign from Russia that used ChatGPT to generate social media posts promoting a fake think tank called the International Burke Institute. The campaign aimed to manipulate public opinion and influence political outcomes, and its infrastructure included a website with copied and misattributed academic work, as well as a 'sovereignty index' that cast Russia in a favorable light. Although the campaign's immediate impact was limited, its elaborate construction and use of AI as a supporting tool make it notable. The operation was exposed due to its use of ChatGPT, which led to the discovery of the broader influence campaign.

10. Beyond Recall and the Illusion of Competence
The author discusses the role of AI in programming, arguing that it's not about who writes the code, but rather about understanding the system and making architectural decisions. They suggest that AI can be used to write boilerplate code and perform tedious tasks, but developers should keep the important parts, such as understanding the problem and making decisions, for themselves. The author also notes that AI may push developers towards a more architectural role, focusing on systems and integration rather than just writing code.
