Simon Willison's prediction, while lighthearted, underscores a genuine inflection point where open AI models are becoming a subject for mainstream institutional commentary. The very notion that the Vatican might engage signals that the debate is shifting from pure technical capability to broader societal impact. However, the forecast arguably overestimates the speed at which such high-level institutions formulate positions on specific technical paradigms like "open weight." The more immediate takeaway is the continued mainstreaming of open-source AI as a philosophical, not just practical, alternative to closed corporate development, a trend that may influence investment and policy discussions far more than any papal statement.
