What you describe, (future "business leaders" wanting IT to be like an "app store) isn't that different than what we have now, which is executives viewing IT as a magical black-box, which is really all an "app store" is too--a magical black-box that "safe" computer programs come out of.

So, really, how will those unrealistic expectations be any different than the current generation of executives unrealistic expectations that we should all work 60-hour weeks for 40-hours of pay, and be "on-call" at all hours we're not in the office including (but not limited to,) nights, evenings, weekends, and vacations?

It's just the next iteration of unrealistic expectations, all being drummed into young business peoples' heads.
