Is it the good old wait and watch strategy or Google just doesn't have it good enough?
Chatgpt is eating more and more Google's lunch and Gpt 4 is landing in a few weeks. Microsoft seems to be on fire yet the big G isn't doing anything.. what gives?
Remember that ChatGPT's core competence is bullshitting; it's a huge mistake to say that it "hallucinates" when it gets wrong answers because it does the exact same thing when it is right and when it is wrong. It's just right sometimes and other times it is wrong. It's unlike human perception where hallucination really is a disease process.
Microsoft jumped in with both feet because the core of their market has always been products that make people feel like they're productive when they are screwing up... Like Excel.
Whatever ChatGPT generates needs to be double checked anyway. If you're relying directly on ChatGPT's output than you're probably making a mistake or might make one later.
