What systems are the most likely to not be used anymore in the Olympics?

Question

I need to know things like touchpads etc.

Answer 1

Boxing scoring system

it was a complete and historic mess

Answer 2

Touchpads are a standard for swimming. With how close races are now-a-days it would be very hard to hold a swim meet without them. They are vastly superior to hand timing and judging a finish by eye. These are antiquated systems that are sure to never return. The Touchpad is here to stay. It's a wonderful thing. If you've ever tried to run a swim meet without a touchpad system, after running one with it... you would agree with me.
