I don't understand how anyone can watch how blatantly Grok is manipulated to answer the way ownership desires it to and then act like the other LLM chatbots couldn't possibly be similarly but less obviously compromised to produce responses in whatever way corporate interests and priorities dictate.

NASA's OSIRIS-APEX just flew past Earth, making a course adjustment to asteroid Apophis in 2029. Apophis will come very close to us that year & could hit in the future.
OSIRIS-APEX will tell us a lot about Apophis...assuming the mission survives budget cuts. 🔭🧪

🚨Airbus has just confirmed to me that this issue does indeed relate to single-event upsets, also known as bit flips🚨
This is pretty massive.
There is scant detail so far but they say "solar radiation" has caused problems for some aircraft.
This *could* be related to single-event upsets, where cosmic rays trigger computer errors. I've asked Airbus if they can share more detail.
