Eh, it's still impressive that these systems can write such good code despite pretty much just predicting the next word. I guess it's a matter of perspective. You can either be astounded by how much it can do relative to your expectations from 2018 or you can be skeptical relative to the volume of excitement. I think some excitement is also people extrapolating to the future: if predicting the next word gets you this far, what happens when you actually try to make it good?
