It is often said that without Maxwell, Einstein would have not been able to conjure his theories on relativity. In fact, Einstein once remarked that Maxwell's effect on the universal perspective of reality was "the most profound and the most fruitful that physics has experienced since the time of Newton". When looking at the technology that relies on Maxwell's equations, it is evident that without them, society would be severely less advanced.
Some examples of technology that rely on Maxwell's equations include...
Generators / (non-nuclear) Power Plants
Phones
Computers
Bluetooth
Satellites
Society without these technologies does not seem very ... modern.
It also seems that Newton and Einstein did not contribute to any of these inventions that have completely revolutionized and interconnected the world!
