> Maybe I'm missing something, but this is more like sql-injection with php/mysql - yes, it's an issue and yes, we need to be aware of it.

It's like an SQL-injection without a commonly accepted solution. And that's why it's a serious issue.

I know how to handle potential SQL-injection now. And if I don't I can just google it. But were I that informed when I wrote the first line of code in my life? Of course not.

Now the whole world is just as ill-informed about prompt injection as I were about SQL-injection by the time.
