So they registered the domain "www" just like they could have registered "google" or "lol".
You can access Google by typing:
- google.com (domain name)
- www.google.com (subdomain)
The same for the domain in question:
- www.ai (domain name)
- www.www.ai (subdomain)
~~The reason why typing ".ai" or "ai", etc. In your browser works is in IMO due to the internals of the browser that automatically adds a www in front of the domain if it can't resolve it because historically so many websites run on http://www.example.com and neglect to setup http://example.com~~
So to take my example from above: The registry responsible for the AI TLD set up a website on the domain name "www.ai" but neglected to set it up on the subdomain "www.www.ai"
Instead, they set it up on the TLD "ai" which is indeed very unusual.

Edit: as pointed by another comment (https://news.ycombinator.com/item?id=31690379) there are actually TLDs with A records which is the case here.
