Tin snips are similar to scissors - they are a combination of two wedges (the blades) and two levers (each blade and the handle it connects to) joined at a fulcrum (the hinge.)There are many types of simple machines. Tin snips would be a first class lever, as the fulcrum(pivot) is in the middle.

Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
some lever simple machines are a stapler, scissors are a lever and wedge, there is lever machines is a car.
a pulley,a wedge and a lever
