I'm talking about a precise, technical, scientific definition, that scientists all agree on, and which doesn't rely on the definitions of other words, and can also be reliably tested.

There has been constant debate about what consciousness means among scientists, philosophers, psychologists for as long as the word has existed. And there has never been any consistent and agreed upon test for consciousness.

The Google definition of consciousness is: "the state of being aware of and responsive to one's surroundings."

By that definition, a Tesla self driving car is conscious, it is aware of and responsive to its surroundings...
