Episode notes
AI Rewrote The Core Laws Of Software
- Ben Horowitz argues AI breaks two old software laws because capital plus GPUs can now compress years of engineering and erase traditional lock-in.
- He says code, data migration, and UI moats weaken when AI agents use software instead of humans.
Audit Your Real Moats Before You Pivot
- Be brutally honest about what your company truly owns before assuming AI will destroy it or save it.
- Ben Horowitz contrasts weak SaaS categories with Navan's real moat in supplier relationships, global travel inventory, budgeting integrations, and a hard-to-reach travel manager buyer.
AI Investing Now Requires Physical Infrastructure
- Ben Horowitz says AI is forcing America to rebuild physical infrastructure, not just fund software startups.
- He cites shortages in rare earths, electricity, manufacturing capacity, and efficient chips as reasons a16z raised far larger funds.
