"Students don't need to learn grammar and syntax and really any vocabulary. AI assistance lets them understand higher level German concepts without needing to know how to conjugate for gender and number or remember if a noun uses der, die, or das."
You see a lot of examples of things that seem absurd when applied to non-technical topics, but as soon as you apply them to computers all skepticism goes out the window. If I told you I have a person who speaks perfect English but frequently lies and outright makes things up, you'd say that's a politician and not to be trusted. But if I say I have a computer with those same properties, suddenly it's the most amazing thing in the world, and we should implicitly trust it to make our decisions and educate our children.
