It’s a cycle to move the window on acceptable discourse. This is at least the third time Grok has been configured to say something outrageous: holocaust denial, white genocide, now Mechahitler. When people react with outrage, they dial it back a little (but not all the way back). Repeat.

Trump does the same thing: go too far, backtrack partially, go even further, backtrack partially. Each time, the transgression is a little less shocking.

Grok is working as intended.
