We have quite prevalent “code objects” too, tweets etc. we sent out on the internet to solve our problems. They do act as agents though, and are sometimes not successful. And you do not code for operations but for virality in an execution machine that is being optimised for this operation via specialisation of its components to be collaterally, obsessively specifically extremist.
We had "tweets" in the 1980s. They were called "usenet posts" and they were not restricted to 280 chars.
The core/key idea of agents in the 90s was that the agent would actually interact with services on your behalf, and reduce the level of interaction you were required to engage in without reducing the specificity of the interaction. That has not happened.
