Replaced every bottom-of-section 'See also:' block with inline Org-mode file: links at the first natural mention in body text. All 29 files across the economics directory now use wiki-style inline cross-references rather than standalone reference blocks.

#+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 [[file:verification-appliance.org][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. This [[file:cost-structure.org][cost structure]] — zero marginal cost per additional user — is what makes Lisp economically viable at scale. The [[file:self-driving-lisp-machine.org][self-driving Lisp Machine]] is the hardware endpoint of this economic logic. For the biological analogy that explains why Lisp architecture is a natural outcome of complexity pressure, see [[file:biology-parallels.org][biology parallels]]. For the historical precedent, see the [[file:comparison-with-symbolics.org][comparison with Symbolics Genera]]. The [[file:ai-industry-impact.org][impact on the AI industry]] is the market-side consequence.
