They are disinformation sources with biases controlled by those who have enough money to create them. All of these companies are in a race to become the source of "truth" for our societies. Every time somebody says "I asked ChatGPT/Claude/Grok/Gemini about this and it said ..." they are laying themselves open to lies and manipulation.
You wouldn't ask Sam Altman/Elon Musk/Jeff Bezos as unbiased sources, so don't treat their products in that way. Just as Fox News was a way for Murdoch to infect society, these machines take it to the next level of insidiousness.
