I'm guessing it's not that technical experts will be choosing this path, but rather companies. Once it's "good enough", and much easier to hire for, etc...you hire non-experts because it works most of the time. I'm not saying it's good, just that it's a somewhat likely outcome. And not for everything, just the places where they can get away with it.
nah. when functional safety enters the room (as it does for hard real time) then engineers go to jail if they sign off something unsafe and people die because of that. since the challenger disaster there is an awareness that not listening to engineers can be expensive and cost lifes.
