To understand a key reason artificial intelligence requires so much energy, imagine a computer chip serving as a branch of the local library and an AI algorithm as a researcher with borrowing privileges. Every time the algorithm needs data, it goes to the library, known as a memory chip, checks out the data and takes it to another chip, known as a processor, to carry out a function.AI requires massive amounts of data, which means there are the equivalent of billions of books being trucked back a...
