The variety of tasks that it is solving now and will continue to solve in the next 5 or 10 years will also increase exponentially. As such systems evolve, they naturally become more intuitive, normal and easy to use for the public. Once considered highly mechanical machines with open roof tops and bicycle wheels, resembling more to a horse-cart (than a car as we think in modern terms), which only a particular section of people could afford, not just due to the cost but also the fuel availabilities, now has become highly cheap, comfortable, fuel efficient and safer. Electric cars are even replacing the brilliantly engineered mechanical components into more simpler ones that require minimum maintenance and are much safer for the environment. And let's not get started on autonomous cars.
