I was taught some math to deal with analyzing circuits but it isn’t calculus. Mostly algebra and maybe some trig every now and then. and for digital circuits it’s even easier.
Still, mechanical circuits may have some utility in harsh environments. JPL said it was working on a concept probe for exploring Venus that is purely mechanical. Though to be honest I think the silicon carbide chips in development hold more promise.
