With computers coming into our world, our reality became digital. Calculations have become easier to do, although it took some time for society to catch up: back when I was still in college, we were allowed to use programmable calculators for the first time in an exam. Rather than study for the exam, I wrote a program that could solve any problem the exam might ask of us. When the exam came I saw the assignments, and realized I'd be out of the room in the time it would take me to input the problems, and write down the outputs. So I solved them with only the normal calculator first, and then checked with the program. Oddly enough, my programming had also made me knowledgable about the theoretical matter of economics.
