I don’t think that a machine intelligence would learn at the same pace as a human. Clock speeds of current computers are on the order of a million times faster than in the human brain (as mentioned in the article). Also the ability to work at 100% productivity without interruption or the need to rest greatly reduces total learning time. Add to this the flawless recall of all previously learned knowledge and you arrive at a capability for machines to vastly outpace any humans ability to learn.
