Oh wow, that's exactly the opposite of how I feel, and conversely, I am that developer who gets itchy when his work doesn't go to prod quickly enough and gets defensive on code reviews.

Sure, part of the fun of programming is understanding how things work, mentally taking them apart and rebuilding them in the particular way that meets your needs. But this is usually reserved for small parts of the code, self-contained libraries or architectural backbones. And at that level I think human input and direction are still important. Then there is the grunt work of glueing all the parts together, or writing some obvious logic, often for the umpteenth time- these are things I can happily delegate. And finally there are the choices you make because you think of the final product and of the experience of those who will use it- this is not a puzzle to solve at all, this is creative work and there is no predefined result to reach. I'm happy to have tools that allow me to get there faster.
