Human

Related but an aside - Lately I've really been wondering if Skynet actually is the next evolution.

That humans, like all animals before us, are a stepping stone and there is actually no avoiding machine overlords. It happens to literally every existence of life across the universe because the final emergent property of energy gradients 100% leads to pure logic machines.

At least Fermi's paradox helps me sleep better at night.

If we assume that the many worlds interpretation has a basis in reality, then we can consider the following metaphysical angle. The evolution around us is our world line with the physical laws we are familiar with. And indeed the natural and inevitable progression of this world line is a machine world, just like a massive star inevitably collapses into a black hole, at least under our physical laws. However in the MWI, our world line may split into two: one will continue towards the machine world as if nothing happened, while the other world line will experience a slight change of physical laws that will make the machine world impossible. Both world lines won't know about the split, except by observing a large scale extinction event that corresponds to the other world line departing. IMO, that's the idea behind the famous judgement day.
