You could say the same thing for sending a Happy Birthday text, versus a hand written letter or card. Nothing is stopping a person from sending the latter today, and yes they are more appreciated, but people also appreciate the text. For example, if you're remote and perhaps don't have that deep of a relationship with them
If a friend of mine sent me some AI generated slop for my birthday I'd be more offended than if they just sent me a text that only contains the letters "hb"
