A new pope can start making a difference in the lives of a lot of people as soon as tomorrow. Proving the existence of a Higgs boson won't matter to nearly everyone for many years, if it ever matters. In the past new physics has eventually lead to new engineering which lead to new products that change peoples lives. In this case I'm not sure that will happen, given the energy needed to reach the new physics. At most the engineering needed to reach those energy levels might spin off new products, but they're not likely to be drastically new, just an extension of existing products.
