Everything is analog, your rise time, your standing waves, your sensors and everything has parasitics. My rule of thumb is that anytime you tell yourself you will avoid learning something in electronics you will eventually have to learn it. That said, you can get a very long way by knowing almost nothing at all beyond high school science and playing lego, and I'm not talking about arduino at all. Need an Analog Front End? Take one from a reference design, take their code while you are at it. Want to know what is messing with your circuit? Learn and understand Maxwell's equations, or put it on a scope and google about. If you want to get products manufactured there is a lot to learn but if you do normal well understood things you don't need to be brilliant or talented.
