I wished I lived in the authors world. A world where you don't have to maintain the code you wrote- or worse yet, someone else wrote. Where you could declare a program "done" and walk away and never have to revisit it. A world where "mostly works" is good enough- secure in the knowledge that you're not going to be rousted out bed at 2 in the morning on a weekend because some server in outer Mongolia hit that corner case you never thought to test. A world where all programs are small enough to fit into my head, completely, in all details. So I could simply know, if I change this, that will break.

That is not, unfortunately, the world I live in. If it is the world you live in, more power to you. Count your blessing and live happily. But the rest of us need all the help we can get.
