Somehow the NPCs never learn

• NON implies denialism aka denying perceivable for suggested.
• PLAYER implies playing a game/gamble aka ignoring given choice by taking a chance.
• CHARACTER implies a symbol marked or branded on the body aka any creed held onto as self, while playing out together.

As for learn/læran - "to teach"... https://www.etymonline.com/word/learn Teaching self implies learning for self and vice versa aka ones perception growing discernment within all perceivable.

That's how learning works within singularity...many students under few teachers implies plurality, which cranks out schools of NPC's.
