Indeed, I'm curious how much better/worse one human with "one agent" could do that same functionality in a OS from scratch. Last time I did this exercise, I took Cursor's shitty attempt from "millions of lines of source code" to about ~20K (https://emsh.cat/en/one-human-one-agent-one-browser/), and seemingly one of my conclusions still hold true ~1 year later:
> One human using one agent seems far more effective than one human using thousands of agents
