Timeline+of+Figure+Skating

As you can see, in 1882 at the Olympics, single jumps were being done and by 1997 and still today, quadruple jumps are being done at the Olympics. This leads me to ask the question, will figure skating jumps continue to get more difficult? In 30 years from now will there be skaters doing 7 rotations in the air at the Olympics? Is that possible? At what point will it be impossible for us to be able to make figure skating more difficult?
