Replace monolithic passepartout-economics.org with directory of org-roam style nodes, each with :ID: property and cross-references using [[id:uuid][title]] format. 27 nodes organized by theme: - Core: index, triad overview, agora, stoa - Revenue: verification appliance, domain gate packages, evaluation harness, skill marketplace, agora usernames, PDS service, compute marketplace - Strategy: investment thesis, moats, licensing, patents, AI industry impact - Analysis: lisp economics, sufficiency flip, time estimates, cost structure, gate rule encoding, upgrade lifecycle, biology parallels, symbolics comparison - Big money: verification monopoly, infrastructure lock-in Old file kept as archive with redirect links to new structure.

#+title: Why Lisp Is Economically Viable Now

The 1980s trade-off was: C is cheap enough for the market. Correctness is a luxury the market cannot afford. The 2020s trade-off is: C is expensive for the market. Incorrectness has become the dominant cost of software. Lisp's verification infrastructure is now the cheaper option.

Four transformations flipped the economics:
|
|
|
|
1. **Memory is free.** 40MB runtime is noise on a $20 Raspberry Pi with 8GB RAM. In 1980, DRAM was ~$5,000/MB.
|
|
2. **Transistors are free.** Modern ARM Cortex-A72 has billions of transistors. GC and type dispatch cost nothing because the transistors are there whether used or not.
|
|
3. **Complexity saturates human verification.** Systems are tens of millions of lines. Testing is necessary but insufficient — zero-day vulnerabilities prove bugs survive all testing. Formal verification is the only known path.
|
|
4. **Cost of failure exceeds cost of verification.** A single breach costs millions. Regulation mandates provable compliance. Proving correctness is cheaper than not proving it.
|
|
|
|
The verification appliance (AGPL symbolic engine + RISC-V Lisp μcode on FPGA) costs $5,000/year and replaces $500,000/year in compliance audits, breach litigation, and regulatory fines.
