For example, how can we dig holes from the United States to China faster Use a shovel to dig from every 2 seconds to every 1 second. There is an upper limit. If it is too fast, the shovel will break (increasing the clock frequency of the processor will increase the energy consumption, and there is an upper limit on the energy consumptio ...
