.io is assigned to the British Indian Ocean Territory
The point I was trying to make above ("who cares...") is that you can use any domain you want! You don't need to use a specific ccTLD (.ml would be the example I was referencing) in order to insinuate your machine learning applications.
But I/O is SV culturally derived secondary meaning to .io (British Indian Ocean Territory), there is no reason to have ascribed it. At least with .ly people are incorporating the ly as part of the name like when people register a .in (India) for their cryptocoin project [name]co.in
