Do they believe that it's likely to scale as high as "standard" LLMs? Or is this another state space machine moment where it turns out to be equivalent to them?
Many research groups have been trying to implement this idea, recent paper from Meta comes to mind: https://arxiv.org/html/2412.09764
If they believe it’s likely to scale, they will try to scale it, so we will either hear about it in a few months, or we won’t.
