With all of these questions and nobody understanding it, I'm starting to doubt myself.
But my impression was that it's like a digital breadboard emulator, but in hardware. So you essentially have a digitally programmable hardware breadboard. So as one example, normally if you would need a resistor in a circuit, instead of physically putting a resistor there of the correct strength, you can do so digitally, and you dont have to physically mess around with a resistor.
