Prediction vs Reality

Overview

Accuracy: 0 exact matches, 27% theme match (8 out of 30 stories). Saturday January 17 was dominated by ASCII rendering deep-dive (#1, 1077pts) - a completely unexpected technical graphics piece. AI developer replacement debate (#2, 544pts, 428 comments!) and Claude Code in Rollercoaster Tycoon (#3, 497pts) persisted from previous days. The Dilbert Afterlife Scott Adams piece (#6, 509pts, 336 comments) was a major cultural commentary surprise. Our Palantir ELITE follow-up predictions did NOT materialize at all.
