But that's not why people reject the idea that
Language can be learned by reinforcement.
They reject it because they simply don't
understand the true power of reinforcement
learning to shape complex behavior. They just
don't understand reinforcement learning.

Reinforcement learning is well understood.

The processes involved in real reinforcement learning (perhaps that's not
what you are talking about?), as currently understood are so vast that no
one person is an expert in every area. Further, no one involved in the
science will say that these processes are understood in any kind of complete
sense - that's why there is still a lot of ongoing research. Perhaps you
meant that the silly toy misrepresentations of these processes are well
understood by those that misrepresented the processes in the first place.




There are also demonstrations of the evolution
of behavior.

You might think about the limitations of Richard
Dawkin's biomorphs as a possible problem with
trying to evolve a behavioral network by RL.

Another example Pinker makes reference to is the
imitative behavior of chimpanzee. One example was
a chimp that seemed to imitate the washing of
dishes but the dish wasn't necessarily any cleaner
after imitating the rubbing motion and this is
apparently typical. The chimp did not twig to the
purpose or goal of rubbing the dish was to clean it.

Autistic people apparently have a similar problem.

There is nothing wrong with their short term memory
indeed they can have a better than normal memory for
facts. Their problem is limited analytical powers,
one being understanding the intentions of others.
