Throughput is indeed king for the standard-tier mindshare-capture play. But there are many who would pay multiple times the current cost for agentic systems for engineers and executives, if it meant a meaningful reduction in latency. The economics could work extremely well.
Impatient execs can also be painful. EDIT: Writing this while I am waiting for Codex to complete, so I may enjoy slow AI more than the usual developer ;-)
The economic effect of latency is measured not by the incremental productivity itself, but by the combined economic downforce of thousands of resulting HN and Reddit comments :)
