I think in some sense current AI is actually conscious and it can certainly understand what you're saying. For exmple, WhatsApp's Meta AI can actually hold a free flowing conversation which it couldn't do if it didn't understand what I was saying and it's uncannily like a human: this thing is deep in the uncanny valley. So, is it conscious? No, not like we are, but since consciousness can't currently be defined, then perhaps it is on some level? Given that, it's reasonable to think that a fully conscious AI will eventually be built and perhaps sooner than we think.
