Over six weeks this past summer, the AI industry began answering a question every business will soon face: once the model itself is cheap and everywhere, where does the value go — and who actually controls a capability once it exists?
A member of Purdue's AI Competency Industry Advisory Board, Darwin Ling, has been writing about AI's development and penned three connected pieces showing how the answer takes shape in three moves. The Purdue alum is founder and general partner of Good AI Capital, a Silicon Valley-based seed-stage venture fund investing in the constraint layer of AI — power, capacity and trust.
The idea: "The Week the Frontier Went Two Directions at Once" argues the frontier has split — closed models are governable and therefore vulnerable; open-weight models are ungovernable and therefore unstoppable. The guardrail layer comes apart from the capability itself.
The money: "The $0.50 Barrel of Intelligence" shows the market repricing around that same axis. As intelligence commoditizes toward zero, value migrates to the layer that decides which model to trust — and can prove it.
The proof: "The Guardrail Only Bound One Side" is the thesis meeting reality: in a live security breach, the closed models wouldn't help with the forensics, while a self-hosted open model the company controlled itself could.
Read together, they provide a critical throughline, mapping where durable value settles once intelligence is free, and why trust becomes the asset a business can actually build on.
