One way of thinking about it, is to think of some kind of 150 in 1 Electronics Play Kit.
After spending a while making a circuit on it (using springs and wires, or similar), at some point you will want to move on to another of the 150 experimenters projects.
So in order to do that, you will have to "destroy" the existing circuit.
Therefore what you are doing, is similar to that.
In a sense, software is "destroyed". Because you load it up into your computer/MCU, and at some point (probably) change it to something else (another game or something), or switch the computer/MCU off, and the ram "forgets" it all.
I suppose the video is showing an accurate depiction, of your real life activities. So although not liked by everyone, the destruction's at least tell a story.
Anyway, seeing the sudden fire and hammering, came as a really big surprise or shock
Sorry if I over-reacted slightly.
GPS is probably a mystery (as to how it works) to most/many people. So making your own, is a very interesting and impressive thing to do.
Next step is to buy a giant firework, and send your own GPS satellites up. That will be REALLY impressive
