That's an argument for cheap massive parallelism, which is what's behind the recent math breakthroughs, not expensive low latency serial compute.
Regardless, I think both things are great, horizontal (more approaches) and vertical (deeper approaches). And both are made more practical with faster inference.
Low latency is a big deal but the immediate use cases are somewhat different in the short-term (more serial coding workflows) rather than pure math research which is effectively massive-scale search through a tree of possibilities, which is where you want throughput and low cost per token, rather than high speed per token.
