I will grant the claim that modern jets are easier to fly than older piston or turboprop airplanes WHEN EVERYTHING IS WORKING.
However, it is the times when things are going to sh!t that experience counts. That is when canned procedures no longer apply, and the pilot has to think, plan, fly, and review contingencies all at the same time. That is when a 150-hour MPA will likely fall apart rather than be a helpful part of the crew.
It is NOT the sunny day VFR flight that is the problem for the low-time pilot; it is the night, IMC, icing, low-fuel fight that will become problematic in a hurry, and fatal if not dealt with properly. IMO, that is the difference between a successful water landing and evacuation in the Hudson, and a heap of burning parts & bodies in Buffalo.
Someone is bound to ask why the experienced AirFrance crew didn't turn around before hitting that thunderstorm over the Atlantic. Good question, but we aren't even sure who was flying at the time...
Modern airplanes are very forgiving -- to a point. However, after that point is reached, the margin between success and disaster is very thin indeed...
