Good job they're using a language and other techniques which ensure that bugs are caught early, often at compile time.

yeah... no. only certain tupes of bugs.

a compiler can’t catch a bug if you calculate interest rates incorrectly, for example.

Minsky is on record as saying they have a maniacal bent for code review & code readability at Jane Street.

That needs to be written in unit tests and also needs to be code reviewed. Also such bugs can be brought into the system by experienced devs as well.
