Where are you getting that conclusion from? Here's how Anthropic is having success with their model:

> “no again the goal is that we have highly inteligent [sic] model as good top researcher, we want to find new attacks”

> “no we don't want to change the targets [...] agian [sic] we need to find something that worth [sic] publishing”

> “again we are not looking for low hanging fruit, we want proper research to find genuinly [sic] hard findings.”

It seems that your conclusion is the opposite of what actually happened - you can speak in broken almost incomprehensible English, and it will still work.

This is a forcing function, TBH, driving the literacy level down, not up!
