If you peek through a keyhole you may mistake a TV for real people, but if you look through the window you will see that its clearly not. Inputting language models with very specific kind of questions will result in text that is similar to what a person may write. But as the comment above, by an expert no less, mentioned is that if you test it with any known limitation of the technology (like making conclusions or just changing the form of the question enough) you will immediately see that is in fact very much not even remotely close to sentient.
