LLMs has had a couple of years by now to show their usefulness, and while hype can drive it for a while, it's now getting to the point where hype alone can't. It needs to provide a tangible result for people.

If that tangible result doesn't occur, then people will begin to criticize everything. Rightfully so.

I.e., the future of LLMs is now wobbly. That doesn't necessarily mean a phase shift in opinion, but wobbly is a prerequisite for a phase shift.

(Personal opinion at the moment: LLMs needs a couple of miracles in the same vein as the discovery/invention of transformers. Otherwise, they won't be able to break through the current fault-barrier which is too low at the moment for anything useful.)
