Once upon a time there were engineers that used software. Just like any other tool, and usually in combination with electronic, electrical and mechanical equipment, all of them being very well aware of the laws governing it all.

But it was so great as a tool that some engineers didn't want to deal with the burdens and limitations of the physical world, and started focusing on software more and more.

Then the software engineers came, for whom the physical and mathematical aspect of the whole thing was just a distant history lesson (and preferably a problem in someone else's computer).

And after software engineers, the only constant in the entire ordeal will remain: engineering, in a shape or form that very likely nobody can predict right now.
