Overall, I think it’s good for logic skills: Putting the pieces together in various ways, coming up with different results. “What if…this… what if that…”…
It’s thought experiments. I think the only danger is when it negatively affects someone’s life.
But taken in a spirit of fiction, I don’t see the harm in it. Lateral thinking, logic development – the context in which it forms to me isn’t quite as important as developing the skill sets to be able to bring boat loads of data in, form a hypothesis (what if) piece things together, come up with conclusions, scratch the hypothesis and try another….
Sometimes I can almost see the connections in his brain happening as he’s talking. Same skills can be appplied in 20 years to figuring out a difficult systems malfunction at a power plant, or a difficult AI conundrum.
