I'm not saying I agree with AI being shoehorned into everything, i'm seeing it being pushed into places it shouldn't first hand, but strictly speaking, things don't have to be more reliable if they're fast enough.
Quantum computers are inherently unreliable, but you can perform the same calculation multiple times and average the result / discard the outliers and it will still be faster than a classical computer.
Same thing like back when I was in grade school and teachers would say to not trust internet sources and make sure to look everything up in an physical book / encyclopedia because a book is more reliable. Like, yes, it is, but it also takes me 100x as long to look it up, so ultimately starting at Wikipedia is going to get me to the right answer faster, the vast majority of the time, even if it's not 100% accurate or reliable (this was nearer Wikipedia's original launch).
