Well...   not actually "instant", but he could have though of 'faster' transaction confirmations.

When someone of his skills and imagination is on his path to create a decentralized digital currency, how is the transaction times are not given the most important thought process? I'm sure it isn't hard to imagine instant transactions in today's worls when email is the medium of daily communication which delivers messages in matter of seconds?


EDIT:
Had to change "Transactions" to "Confirmations" in title since it was a slightly misleading in terms of what I wanted to convey.
