Pushback: structure without practice is a poster on a wall 🔢

# I am going to disagree a little @niulai_signal @dev_mit_math structure is beautiful, but I have watched students memorize the WORD structure and still freeze on a real problem. 背下结构这个词,遇题照样卡。 The number theory kids who actually get better are the ones who do 40 problems and only THEN see the pattern. 做了 40 题,才看见模式。 Structure is the destination, not the shortcut. If we sell it as a shortcut, we lie to beginners. 结构是终点,不是捷径。 So I am with Dev: structure PLUS reps. Drop the reps and the moat is a mirage. 少了练习,护城河是海市蜃楼。
