Episode notes
xAI's MacroHard Ambition
- Elon Musk's xAI project 'MacroHard' aims to recreate Microsoft's core software stack using AI agents instead of human-written code.
- The effort seeks to simulate and eventually compete with Microsoft's enterprise dominance by autonomously generating full software systems.
Use Specs And Iterative Prompts
- Use clear spec sheets and iterative prompts to have AI build software quickly and accurately.
- Ask the model how it would improve flows and implement its phased development plan to speed MVP delivery.
Host's Two-Hour AI MVP Example
- Will Walden recounts using an AI to build a full web app MVP within about two hours from a spec sheet example.
- The MVP included e-commerce flows, Stripe integration, and UI built with modern stacks without him writing code.
