Goddamn. Imagine being so creatively bankrupt that you can't even write a simple birthday message for a child without Robot Daddy's help. I'm so glad the AI bubble is coming crashing down, it couldn't have come sooner.
AI sucks but I think it's unfair to assume everyone feels comfortable, capable or self assured enough to write something of their own.
That is such a stupid argument to make. It is not really so much what you write but the thought behind it. And the thought behind using AI is always signalling something negative. Not writing anything but your name would be more personal and heartfelt than that.
