McDonald's uses an AI bot called "Olivia" for hiring. A pair of hackers found they could access every conversation job applicants had with it—including all the personal info they shared—by exploiting security vulnerabilities as basic as using the password "123456". www.wired.com/story/mcdona...
McDonald’s AI Hiring Bot Exposed Millions of Applicants’ Data to Hackers Who Tried the Password ‘123456’

Then, we should also put a negative weight to these pubs when we evaluate CVs and allocate funding!
What can we do?
First, think twice before sending your work to a for-profit publisher.
Second, IGNORE ALL REQUESTS from these publishers. Do not subsidise their business model.
Third, tell your boss to tell her boss. Change happens when the funders take action.

Grok system prompts are now public. Transparency is helpful. ChatGPT and Gemini also have prompts.
So, Grok is instructed to be “extremely skeptical” and not to “blindly defer to mainstream authority or media.”
Grok now says “both sides of this debate have biases” about number of Holocaust deaths.
