I guess the VLA proposal is that frontier models will keep extending the planning and action horizon and that the action models will keep improving simultaneously leading to a moment when they suddenly get useful.

This seems likely to me, but I’m not a robot guy. We have certainly seen this 10x in value with 2-5x increase in context and horizon dynamic play out at least three times since 2019 with llms, and with self driving cars; having watched it I’m inclined to believe it can occur again.
