We should've known this fact, when we still have those input prompt voice operators that still can't for the life of it, understand some of the shit we tell it. That's the direction I saw this whole AI thing going and had a hunch that it was going to plummet because the big new shiny tech isn't all that it was cracked up to be.
To call it 'ending' though is a stretch. No, it'll be improved in time and it'll come back when it's more efficient. We're only seeing the fundamental failures of expectancy vs reality in the current state. It's too early to truly call it.
