Good info about Video IDs in YouTube URL

This video by Tom Scott explains if YouTube will ever run out of Video IDs that are used to uniquely identify each video on YouTube.


Each YouTube Video has an ID, that is a unique, random and made of 11 characters



He explains different numbering systems Base 10, Base 2, Base 16 and about the one which YouTube uses, Base 64.


73,786,976,294,838,206,464 – Seventy Three Quintillion, Seven Hindered Eighty Six Quadrillion, Nine Hundred Seventy Six Trillion, Two Hundred Ninety Four Billion, Eight Hundred Thirty Eight Million, Two Hundred Six Thousand, Four Hundred Sixty Four


With this number can YouTube run out of IDs for Videos, Tom Scott says, Technically Yes, Practically No.
