Nobody uses those for their intended "national country" use. .io and .ai are tech-focused, .tv pretty much only has tv stations or video providers on it and so on.
Most countries except the USA have their local domain in general usage.
Even the "hacks".
Search "site:.ai Anguilla" for examples. You obviously be little reason to visit websites of Anguillan restaurants, government, telecoms, tourism etc but they exist.
Within Anguilla it's a small signal of a local business.
