an explanation of the joke :D, he is saying more binary in a gigabyte, I get what u mean with the transistors but he aint talking about that, he talks about being able to fit more data (binary, the raw data, ones and zeroes) in the same space (one gigabyte, like 1024^9 or around 1billions spaces for the ones and zerors) bc ofc, it's apple so they somehow can save morr info in the same amount of space, that's whatvhe meant :)
