Karpathy's AI Warning Applies to Marketing: Master the New Stack or Fall Behind
★ max(signal) by Andrej Karpathy · AI Tools
Δ +4680 read ↗
TL;DR — OpenAI co-founder admits feeling behind despite building these systems. Marketing parallel is direct: the gap between marketers using AI as a feature and marketers orchestrating AI workflows is widening fast. His vocabulary (agents, prompts, contexts, memory, tools, plugins, workflows) maps to marketing ops. The 10X productivity claim requires stringing tools together correctly. Key insight: failure to capture AI leverage is now a skill issue, not access issue. Same tools available to everyone. Competitive advantage shifts to those who build mental models for 'stochastic, fallible' systems. Marketers face identical challenge: learn to orchestrate unreliable-but-powerful AI across content, analytics, automation.

Fishkin: Never Ask an AI Tool How It Came Up With That Answer
★ max(signal) by Rand Fishkin · AI Tools
Δ +4200 read ↗
TL;DR — LLMs use the same probability system to explain themselves as they do to answer questions. When you ask 'why did you recommend that?', you get another statistical lottery, not truth. SparkToro tested 100 people asking ChatGPT identical knife recommendation prompts. Almost no two got the same brand list. When asked to explain, ChatGPT fabricated reasoning. Marketers making decisions based on LLM self-explanations are building on false foundations. The only honest answer: 'most likely token based on training data.' Applies directly to anyone using AI for brand tracking, competitor analysis, or content recommendations.
