You Already Trust Code You've Never Read
When was the last time you reviewed the assembly output of your compiler?
I'm guessing never. You write Python or TypeScript or Go, hit build, and trust that something correct comes out the other end. The compiler is a black box. You don't understand its internals. You don't need to.
As InfoWorld notes, when high-level languages first required compilers, many thought no machine could write better assembly than humans. That concern was put to rest long ago.
So why do we treat AI differently?
