Criteria for Resolution:

1. Technological Singularity: It is generally accepted by the professional community that the technological singularity has occurred. If Wikipedia exists, the confirmation will be based on the (honest) existence of a statement on Wikipedia's "Technological Singularity" page indicating that the singularity has happened. In ambiguous cases, a separate market will be created to resolve whether the singularity has occurred.

2. Abandonment of Paper Correspondence: Paper correspondence is considered to be abandoned if more than 75% of people in Germany do not receive or send more than one paper letter per month on average.

Clarifications:

- Technological Singularity: Defined as a point in time when artificial intelligence surpasses human intelligence and becomes capable of recursive self-improvement, leading to rapid and profound changes in society and technology. The determination of its occurrence will be guided by consensus within the professional community and indicated by a statement on Wikipedia.

- Paper Correspondence: Includes traditional letters, bills, official documents, and other forms of paper-based communication. Surveys or studies from reputable sources (e.g., government reports, academic studies, or market research firms) will be used to measure the frequency of paper correspondence.

- 75% Threshold: The abandonment criterion is met if more than 75% of the German population, as determined by reputable surveys or studies, do not receive or send more than one paper letter per month on average.

Data Sources for Verification:

- Wikipedia: The "Technological Singularity" page must explicitly state that the singularity has occurred.

- Surveys and Studies: Data from German federal statistical agencies, academic research, or reputable market research firms measuring paper correspondence habits.

- Professional Community Consensus: Confirmation from leading AI researchers, technologists, or authoritative organizations recognizing the occurrence of the technological singularity.
