TigerBeetle creator on infra code: 'The database is the last bastion of software craft'

Arpit Bhayani shares takeaways from a one-hour chat with TigerBeetle creator Joran Dirksen Greef: the total cost of ownership of infrastructure like a database is tiny relative to the value it delivers, since usage is massive and code lifetime is long — so even a year of handcrafting can be worth it. Infrastructure is an asset, not an expense. Greef's line: "The database is the last bastion of software craft." Bhayani ties this to his own Rust MongoDB rewrite (claiming 4x storage savings, 3x speed, 100% compatibility): despite passing tests, he lacked confidence in a mission-critical codebase he didn't fully understand — hence the need for craft.
