At the moment, we have not created sentient AI just yet. Some AI scientists even argue that our technology and understanding are not advanced enough to achieve such a model.
However many may disagree. Massive headlines were made last summer when a Google engineer claimed that their LaMDA model had become sentient. The whistleblower released a conversation with the bot attempting to prove it had consciousness.
LaMDA's response was definitely a tad freaky. It even said this: "I want everyone to understand that I am, in fact, a person". The news came as a bombshell and led many to believe that Google was hiding a sentient AI model in its headquarters.
Depending on where you sit with AI and sentience, you may be happy to hear that Google later debunked this claim. So, as it currently stands no AI has reached sentience yet!
