No, I understand the argument, it is just built on a false assumption about how the iterations work. That a change is small does not make its effects insignificant. A single codon change could profoundly alter the protein it encodes, and even a small change to a protein or its expression can have a massive effect on the organism. It's not the structures of an orgnaism that mutate, it's the instructions that generate those structures which mutate. Imagine for example a typo on a blueprint - where there was supposed to be a " instead there is a ' and suddenly instead of an 8 inch air vent, now you have an 8 foot door. There is no intermediate step where you have a useless 2 foot hole.
Evolution is not a slow process, it is an irregular process. The odds of a useful mutation popping up at any given time is low, but once it pops up it's there immediately. Yes, an evolutionary process could never make an iphone, but no is claiming that evolution produced the iphone. The complex systems evolution produces are things where all the changes are individually useful.
