First we specified the exact flow of the bits with punch cards.

Then we got assembly and we specified the machine instructions.

Then we got higher level languages and we specified how the memory was to be managed and what data to store where.

Now we have object oriented languages that allow us to work with domain models, and functional languages that allow us to work data structures and algorithms.

The next level may be writing business rules, and specifying how services talk to each other, who knows, but it will be no different than it is now just a higher level.
