Cognitive Overload: AI Maxing, Product Development and the Hidden Tax

Danny McMillan returns after his longest break in almost ten years, with Seller Sessions approaching its tenth anniversary and roughly 1,300 episodes. This is the pilot of a new monthly roundtable with Sim and Matt (Dorian returns next month), moving away from the conversion show format towards raw conversation.

You'll hear how Sim's team runs product development end to end with AI: keyword-scored idea validation, brand director sign-off, Claude-generated product concepts rendered through Codex, and a launch pipeline already booked out to 2027. Matt shares how Productpinion prioritises features from customer feedback, and why prioritisation is the most undervalued skill in the AI era.

The back half tackles the big theme: cognitive load. Danny breaks down verification fatigue, context switching and AI maxing, and why the scarce resource is no longer time but attention and decision quality.

Key Topics

• AI-driven product development - from keyword scoring to Claude SVG concepts and Codex-generated product renders
• Team structure at scale - how ideas route through brand directors to sourcing across UK and Philippines teams
• Hiring in the AI era - why refusing to use AI is now a dealbreaker, and why gutting teams for AI is commercial suicide
• Free local AI tools - Fluid Voice (Whisper Flow alternative) and Meetily (Granola alternative)
• Cognitive load and verification fatigue - the hidden tax of moving from doer to overseer

Key Takeaways

• AI has made product development fun again - unique product concepts generated with Claude and Codex, feeding a pipeline mapped to 2027.
• Augment, don't replace - if someone was worth hiring, AI should multiply their output, not justify cutting them.
• Prioritisation is the undervalued AI skill - just because you can do everything doesn't mean you shou
