Multiple layers make it easy for the PCB traces to route by jumping over from one layer to another to complete the path. Hence many complex circuits can be routed easily.
Also the demand for compact electronic devices boosts the need for multiple layers PCB.
In PCBs with 4 or more layers, supply and ground is separated. This offers isolation between supply and ground pins and hence avoids short circuit.

We are a green energy brand which sells solar water heater. All of our products are almost use PCB. And we want to know whether it is poisonous to human and environment?
Last week we visited a PCBA factory. We were looking at reflow ovens. A lot of them have a metal conveyor belt the boards sit on. On a double sided board, when you put the board on the metal belt, won’t the metal belt knock components off as they are only held on by paste?
I am designing a micro-strip antenna with an HFSS toll, what’s the thickness of FR4 substrate that one should take ?
