If you really want to rail against the journo's hype of the story, then you'd gain some credibility yourself by refraining from statements such as:
"...Researchers from OpenAI found that agents would talk to one another in a kind-of Morse code when forced to communicate and work on a task together."
Which implies that this Morse code type behaviour emerged as a result of the two agents cooperating with each other, and the researchers were un-aware of this and discovered this newly emergent and spontaneously created behaviour.
Which is clearly a total load of bollocks. IF they communicated "in a kind-of Morse code" then it's because they were programmed to.
