In 40 year software designers couldn't figure out that there should be a search function for every functionality that your computer provides.

When we got a form of such search, it searched all of the internet alongside with the functions of your software on your computer. You had to tell it manually what software you have and when it found something you had to fish out the description of what to click to get the functionality you are seeking and then click through some dumb ui to actually invoke it.

Agents are the first thing that can lead you directly from "I know what I want my computer to do." to "Actually doing it."

Success of agents is founded on the profound and sustained failure of all of the software designers and developers ever.
