You don't need that expensive weapons to shot down a helicopter. A gunshot or a RPG are usally enough.
Helicopters during the Vietnam era only needed a bullet into their hydralic system for them to crash. Furthermore did they lack any warning systems that told them that they were taking hits from enemy fire and needed to take cover, so it was often only after other helicopters in the unit saw gunfire that anyone could react.
Todays helicopters are much better in so far that the pilots are more likely to survive a crash.
However, the limitations are still much the same. They can only carry a limited amount of weight, and therefore they cannot carry much armour. They cost much money and they got limitations on range, how much weight they can carry, and they cannot take much damage, and most helicopters in Vietnam couldn't take survive long in the harsh climate since the rotorblades got destroyed by wood and rocks it threw up, and Iraq 2003 British Helicopters also suffered from a short lifespan to all sandydust it threw up.
And helicopters in Vietnam was also limited in their capabilities to operate at night and in bad weather.
So helicopter warfare got its limitations. With a limited number of positions on the map suitable for helicopter transports of men, it was easy for the Vietcong to make ambushes on American helicopters.
So protect the transport helicopters, some helicopters was starting to carry rockets and machine guns. And those huey gunships would later lead to the UH-1 Cobra, the worlds first attack helcopter.
So do I think attack helicopters are obsolete? Not yet. They got much firepower and can take out enemy tanks. And they can provide protection for other helicopters. But on the other hand are they weak, and would probably get replaced by drones in the future.
Few armies got the luxury to move large numbers of troops by helicopter, so I think the transport helicopter will mostly be valuable as an ambulance.
And the Air Cavalry Division in Vietnam had limited firepower since everything had to be transportable by helicopter. And the troops were vulnerable to ambushes when they landed or lifted. And also resupplying the troops by helicopter could be dangerous under enemy fire. And just one single bullet could be enough to down an expensive helicopter with all onboard. Later on would troops be dropped by rope by helicopter so they could clear a landing zone with chainsaws. Or Planes could drop mega bombs in the middle of the djungle, so helicopters could land in the crater.
