For example, the other day I was chatting with it about the health risks associated with my high consumption of grown salmon. It then generated a small program to simulate the accumulation of PCB in my body. I could review the program, ask questions about the assumptions, etc. It all seemed very reasonable. A toxicokinetic analysis it called it.
It then struck me how immensely valuable this is to a curious and inquisitive mind. This is essentially my gold standard of intelligence: take a complex question and break it down in a logical way, explaining every step of the reasoning process to me, and be willing to revise the analysis if I point out errors / weaknesses.
Now try that with your doctor. ;)
Can it make mistakes? Sure, but so can your doctor. The main difference is that here the responsibility is clearly on you. If you do not feel comfortable reviewing the reasoning then you shouldn’t trust it.
