Inevitable indeed. From what they’ve been able to discern, the eruptions occur when the magma finds a weak spot in the crust. The caldera appears to ‘move’ since the plate has crept along over millions of years. Literally a matter of time until it finds another release point.
Correct. My understanding (I'm not sure where I read this) is that a relatively thick / strong area of the crust has "recently"* covered the magma "hot spot", so we should be "ok" for a while, at least as regards a monster eruption. That still doesn't keep Yellowstone from being a very active area!
*In geologic terms.
