You lost me there. Children are pretty intelligent and have no concept of time. I don't see the relation you find obvious and the rest of your points similarly don't follow.
> Therefore, inventing cars was an easily predictable event.
This feels like a benefit of hindsight unless you can call out other obvious and imminent (but not yet existing) inventions.
I don't blame you for immediately rejecting the rest of it. But do hear me out: the point about the inevitability of invention does have real support. Historians call it multiple discovery - tons of things have been invented independently - calculus, the telephone, the jet engine, to name a few.
Neural nets, GPUs, and the scale of Internet text made something like LLMs close to inevitable. Of course, we could debate forever whether any of these on its own was ever inevitable. The point is - society tolerates any cost of a useful invention for the benefit of saving time. So it's reasonable to assume this will be the case with AI as well, which is really happening as we speak.
