I don't know but I know it's an evolution of humans.
How sure are you of that and why?
The universe is all about evolution, the human race is evolving. It's nots to think that AI is in any kind of state now or ever to take over or surpass the evolution rate of human beings, who will harness AI to increase the rate of evolution.
This is a weird argument. The evolution of AI itself is clearly going way, way faster than human evolution. Even if you take a moment before the invention of computers as the starting point, AI has evolved to let's say ant or bird level intelligence in only 100 years. In addition to that, our modern social safety nets etc. have clearly slowed down if not completely eliminated human evolution through the normal natural selection process. Actively evolving our bodies is an option, but it would be either eugenics, genetic engineering or cybernetic engineering. All of them are problematic, but the latter ones are the most problematic:
Cybernetics:
Can you put wheels on a horse? Yep, you probably can, with the engineering being incredibly tricky to get right. But will it ever be able to compete with a car?
Neuralink-like brain computer interfaces and cybernetics in general have the same general issues as the example: Trying to 'upgrade' a million years old legacy 'design' with a modern approach. Again, not impossible, but way harder and less potent than just designing a new system from scratch.
Genetic engineering:
Incredibly long feedback loops: It takes a good chunk of a human lifetime to know for sure whether your genetic hacks actually worked properly. Unless.. You use advanced simulations. At which point you've effectively created AI anyway. And that is in addition to the issue of trying to upgrade a legacy design: genetically engineering 'wheels' on a horse is probably even impossible.
Food for thought: The propagation speed of signals in our bodies maxes out at about 100m/s. The (currently known) theoretical limit is about 300 000 000m/s, 6 orders of magnitude (or 'a million times') faster. AI already operates close to that limit.
This is utterly irrelevant until you are working on a game of instant reflexes - evolution favors the long play.
Exactly, it favors the long play. Why do almost all advanced forms of life have eyes (sensors for light)? It has evolved many times, in different places in the evolutionary tree, which is called convergent evolution. The answer is really simple: because (visible) light is the quickest and most information dense means to gain information about your surroundings and thus will provide an evolutionary advantage always, (almost) everywhere in the universe.
Now think about signal propagation speed again. Our communication networks operate near the theoretical limit. Would a communication network of an advanced alien civilization do that as well? Yes. Yes, it would. The technology would advance until it would reach that physical limit. It is convergent technological evolution.
Now ask yourself whether increasing internal signal propagation speed provides an evolutionary advantage (hint: myelin). Ask yourself whether what comes after us will have an internal signal propagation speed close to the speed of light or not. Look at your phone and computer and realize that they are already there, wirelessly even.
Beyond that, there are tons of other evolutionary advantages inorganic intelligence ('AI') has over us hairless apes: Way higher communication bandwidth, no significant deterioration due to lack of gravity or oxygen or water, more modern cooling system, far easier to scale in both (physical) size and power input (a human runs on about 100 watt and it is very hard to increase that), easier to protect against radiation or elements, incredibly easy to interface with a myriad of already existing sensors and actuators, easy and flexible hibernation, etc., etc.
Most of our evolution hasn't been towards achieving high performance intelligence and rationality (and looking at politics today, it shows :-P). The design of AI however is explicitly trying to achieve that.
So tell me: What comes after humans?
