Earlier quoted context omitted.
Stamping out software is what your Windows/OSX/linux installation CD/DVD is. Microsoft is making a lot of money stamping out (figuratively nowadays) copies of Windows. I think you misunderstood. The product a software engineer makes is not a CD that lands in a person's hand. It's the arrangement of bits that eventually ends up on that CD. The OP is saying there is no way for a machine to arrange those bits.
He understands you. He just disagrees and thinks your metaphor is wrong.
First of all, let him speak for himself. Or do you claim to read his thoughts?
Secondly, no he doesn't seem to understand. The statement he disagreed with was: We cannot put software on the kind of assembly line/stamping process which is obviously a point about the fact that we have no assembly line process for writing new software.
He replied with: Stamping out software is what your Windows/OSX/linux installation CD/DVD is which is obviously missing the entire point. We are talking about writing the software, not putting the software on the disk. It's a distinction you've clearly also missed.
