"Japan is considering building a $1 billion detector called Hyper-Kamiokande, which would be between eight and 17 times bigger than Super-K and would be sensitive to proton lifetimes of 10^35 years after two decades."
All this to possibly detect a single proton decay in 20 years. Now that's some serious commitment!
