PPO replaced TRPO the same way Johnny English catches the bad guy: by keeping it simple
eigenron · x · 2026-11-05
An AI-community joke tweet: the author compares how PPO displaced TRPO to a famous Johnny English scene where the protagonist catches up with the villain using nothing but common sense and simplicity — implying PPO won over TRPO's complicated second-order constraint machinery by being the plainer, more intuitive algorithm. A nostalgic algorithm-history quip for RL veterans.
