You need to define ideate, tools and technologies to answer those questions. Not to mention that it's quite possible humans do those things through re-combination of learned ideas similarly to how these reasoning models are suggested to be working.
Every technological advancement that we've seen in software engineering - be it in things like Postgres, Kubernetes and Cloud Infrastructure - came out from truly novel ideas. AI seems to generate outputs that appear novel but are they really? It's capable of synthesizing and combining vast amounts of information in creative ways but it's deriving everything from existing patterns found within its training data. Truly novel ideas require thinking outside the box. It's combination of cognitive, emotional and environmental factors which go beyond pattern recognition. How close are we to achieving this? Everyone seems to be shaking in their boots because we might lose our job safety in tech, but I don't see any intelligence here.
