Field note
As model competence rises, the bottleneck moves to choosing criteria, packaging questions for people, accepting results, and refusing to treat unread generated text as finished work.
New Runtime reading: The sources are heterogeneous and do not prove a universal law. Together they form a qualified operating-model hypothesis about human I/O and acceptance.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
