Facing Facts

“The definition of insanity is doing the same thing over and over again while expecting different results.” If all we had was ChatGPT, we could say, hmm “maybe hallucinations are just a bug”, and fantasize that they weren’t hard to fix.

The Second Worst $100B Investment in The History of AI?

By any reasonable account the worst investment in the history of AI has to be the over $100 billion that have been invested in “driverless” cars.
