Given it is 21st century, why we can't think of mechanism which will save people in case there is problem with the airplane during flight? e.g. so that cases like MH370 don't happen?
Is this really such a difficult engineering problem?

There are, as many others pointed out, many thousands of systems, saving the aircraft.
But I assume you mean things like ejection seats or parachutes for passengers:
There is indeed already a mechanism to save the passengers of a plane. Not for airliners, but for general aviation planes. It's called the Ballistic Recovery System (BRS). Cirrus built it into their Cirrus Aircraft and named it Cirrus Airframe Parachute System (CAPS).
