Collective hallucinations are common. Mandela effect, people thinking FB is listening to your microphone because they see relevant ads, etc
This is a common phenomenon that all humans pattern match to things we expect. When we learn a new vocabulary word you see it everywhere for the next two days. When we think Claude might be nerfed, we overindex on every instance of Claude underperforming.
The only way to account for this is credulous, hard data. Like benchmarks over time. To this day no one has provided evidence that Claude Code, when fixed to the same thinking level, has had degraded performance.
