It looks pretty clear LLMs don't get us there by themselves, no amount of duct tape, WD-40, etc. gets us past, say, the mathematical certainty of hallucinations.
I mean, we don't know it any more than we don't know someone won't come out with cold fusion tomorrow, but it's a fundamental breakthrough away from where we're at. This isn't some routine engineering project with a guarantee of completion if you're just willing to keep pouring the billions. That's playing the lotto, you can pour away and get flat nothing.
The only difference is they're pouring billions and praying a rabbit comes out of the hat, but it's actually not much reason to expect they're going to pull the cold-fusion level rabbit out of their hat they'd need to get us past bikes.
