It's an interesting coincidence that shortly after Blackrock invested $6 billion into xAI, this platform is suddenly being transformed into a social credit-style system where users are ranked based on vague and subjective criteria like "positivity." 

At the same time, Grok is being aggressively promoted and displayed prominently on every post. Given these developments, it wouldn't be surprising to see a Grok "fact-checking" feature introduced in the near future as well.
