Why Do People Love Voice Search?

The human population is moving toward an astounding 8 billion people and should get there in just two years. By that time, the number of voice search assistants, which is currently over 4.2 billion, is projected to hit the same mark. Not everyone will have access to one, of course, but this is the product of many people having numerous devices -- phones, tablets, laptops, Alexa-enabled devices, Google Home devices, etc. But nothing shows the sheer popularity of voice search options like this incredibly fast rise to equal the global population. Clearly, this is technology that is here to stay. Why is it so popular?
