The claim is largely accurate. Google and Anthropic—both major software companies—have publicly stated that a majority of their new code is AI-generated (Google citing over 50% of weekly production check-ins, Anthropic citing 70-90% company-wide). However, these are self-reported figures from AI-focused firms, the metric typically refers to new code check-ins rather than entire codebases, and industry-wide averages remain well below 50%. The claim is true as stated but could easily be misread as an industry-wide trend.

The claim that AI poses a risk of causing human extinction is supported by credible sources, including peer-reviewed research, the International AI Safety Report 2026, and statements signed by hundreds of leading AI scientists. Even skeptical analyses (e.g., Brookings) do not deny the risk exists — they argue it is speculative and should not dominate policy priorities. The claim is accurate as a statement about the existence of a recognized risk, but readers should understand that no established scientific consensus quantifies this risk as probable or imminent.
