There are speed thresholds that open up new use cases.

Imagine speeding up current agents 10x, you switch from directing agents to pair-vibing on the fly.

Speed them up 10x more, and you get a SOTA model capable of analyzing and rethinking your entire file in between your key strokes. That would make for one hell of an autocomplete.

Pivot over application, going from coding to anything else, and this can easily give computers features previously impossible to make. In video games, fully general characters reacting realistically to arbitrary dynamic situations. In "serious" apps, interactive work with a system that understands your goals and adapts to you on the fly. Hell, even an OS that can tell you "hey, the data you're obviously looking for is in the tab over there, now highlighted".

And that's just tip of the iceberg. I'd personally love to explore the possibilities.
