Is There a Turing Test?

In the fossil record, looking at early hominids, we have this seemingly exponential growth of the brain between about 2 million years ago and now. We might be able to wave at Noctbus, but if they have no perception of the wave, we might try to be communicating with them. And so it becomes kind of an interesting problem, not only in terms of what could we possibly communicate, but how could wepossibly communicate? Like what are even the kinds of information that we should be sending to these Cephalopods, for instance,.
