So – clearly quadcopters are more stable (see all the drones), so why aren’t actual helicopters all quad copters?

So the main basis has been missed somehow so:
Quadcopter drones exist due to the advent of ultra cheap micro-computers.
It is a terrible design for any normal aircraft (highly unstable among other issues) but it is an ideal way to control an aircraft with a *computer.*
Computers can perform simple operations at lightning speed, but struggle with complex multi-variable decision-making (think of the challenges in getting a self-driving car).
The Quadcopter design requires constant inputs, but the actual calculations and actions are very simple, as a result it is much easier for a computer to precisely control a quad-copter than a traditional helicopter. When for a human it would be the opposite, trying to make a quadcopter work without advanced computers would be extremely difficult
