First, a small pet-peeve: technology is definitely not "dismissing the need to reason about how to solve a problem". If anything, it helps us focus on the core of problems. For example, having massive amounts of data, or the ability to analyze it only helps us focus on the actual problems, which are still very present.
Also, I don't think changes to our way of living or thinking about the world are evolutionary in the strict sense of the word (in terms of genetic makeup, etc.) If you actually mean evolutionary changes, there is evidence that these are still going on and that some of these are sticking. In other words, evolution (in the biological sense) is definitely still going on, of course.
As to what can bring us to actual extinction, I'd say probably very few things. What comes to mind:
A very serious disease: It would have to be infectious enough to spread very quickly, probably airborne; at the same time it would have to be very lethal but not too lethal where so many people die that it can't be transmitted. My guess is even something with the right combination wouldn't actually kill off the species.
An asteroid hitting: If we saw this coming, my guess is the wealthiest members of the species would try to go live underground for years while things clear up, but I'm not sure how effective this would be depending on the size of the asteroid.
War: Conceivably, an all-out nuclear war might wipe us out. I think there are enough nuclear weapons for this, the problem would be that most of the attacks would be concentrated on a few countries, but the remaining regions of the world might die off from radiation/famine, etc.
Since the reasons above seem improbable, I'd say the continuation of the species is a safe bet. Where I see us evolving is towards more of a symbiosis with machines, blurring the line between what is human and machine, making great advances towards specific types of AI, though I'm not sure I'd say general AI is a given. This is probably the most important thing to determine our future as a species, how far we can go with AI.
