Quoting Bruce Schneier
Security technologist Bruce Schneier compares writing assignments to gym tasks rather than work tasks. He assigns policy memos to his students not because the world needs more memos, but because the process of writing helps develop essential critical thinking skills. This process involves thinking, outlining, drafting, editing, and continuously revising arguments.
Without this constant mental exercise, critical thinking skills will atrophy. Employers are already noticing the effects of this decline. Schneier shares these insights in a piece exploring how to decide whether to use artificial intelligence for specific tasks.
