Except in a small minority of circumstances "lowering the cost of code" doesnt really help if the code which was lowered in cost was crap code.

High quality code hasnt lowered in cost. Arguably it's gone up actually because more slop needs to be cleaned up.

And, for all people drone on about "customers/the business dont care about code quality they care about results" the indirect side effects of code quality are things they do care about deeply they just cant connect the dots.
