- 1980s: memory K/MB, 1-10MHz CPUs, simple software, testing-sufficient. C fit in 64KB; Lisp needed 40MB and GC cycles. The market chose throughput. - Today: memory and transistors are free (billions on an ARM core). Software is too complex for testing alone. Cost of failure > cost of verification. - Inversion: 1980s said correctness is a luxury. 2020s says correctness is the only affordable option. - Passepartout exploits this: verification appliance for K/year replaces 00K/year in compliance failures.
