Patrick,    (01)

Natural languages are much richer and more flexible than
any version of logic or any programming language.    (02)

Those are languages designed for using very inflexible
computers to solve problems that require precision -- e.g.,
banking, accounts receivable, or storage and transmission
of data without losing or altering a single bit.    (04)

Absolutely not.    (06)

People have been applying computers to natural language processing
since the early 1950s, and they're still discovering more research
problems than useful results.  Many linguists still have a strong
interest in working on such problems.  Unfortunately, the people
with money have lost interest in paying them.    (08)
