Criticizing a 2002 estimate of 5,600,000,000,000,000.000000000000000000 kilobytes, linguist and University of Pennsylvania professor Mark Liberman asserted that it would actually require 48,000,000,000,000,000,000.0000000000000000000000 kilobytes to house a recording of all speech in human history, even at a relatively low level of quality. For the purposes of his calculations, Liberman estimated the total duration of such a project to include 416,390,367 years of continuous audio.
