Lie is a weird way to describe it. They hallucinate answers which is give you an answer they based on probabilities. Its not lying its just lacking in data to give an accurate and correct a answer which will get better with more training and data. Everything else we have so far gets worse. Google isn’t what it was 15 years ago.
I use chatgpt every day to find out answers over google. Its better in almost every single way to get information from and I can only imagine what it’s capable of once it can interface with crawlers.
