If that's the case that's a big problem, because human children are trivially capable of both formulating and understanding uncommon sentences which still make sense.

It might be hard to come up with examples on the spot, but in everyday life you will routinely come across things you need to refer to by negation which are relatively uncommon.

Human children are also capable of walking, but it’s one of the hardest problems in robotics. Things brains can do intuitively, they can do because they have millions of years of evolution behind them.

Of the things the human brain does, I wouldn't say walking is very interesting.

The most amazing property in my opinion is the fact that it trains itself. (Whereas neural networks are trained by external systems).

I suspect it's related to imprinting. To take the example of filial imprinting, the brain must have some hardcoded notion of what a parent looks like. Then this is used to to build a parent detector, and the hardcoded notion is thereafter discarded. Then the newly learnt parent detector is used in reinforcement learning (near parent = good). Keep in mind that this all happens just after birth or hatching, before the visual centres of the brain have had any chance to train.

Really cool stuff.
