It is impossible to evaluate such a statement without knowing
what you have in mind as the requirements of this subsystem. Of
course, it is really meaningless to talk about LOC anyway as the
smallest in LOC is not necessarily either the best or the
simplest to implement.

What on earth is all this LOC talk about? I haven't seen the
like since we used to brag about getting tiny Basic in less than
2K bytes of machine code.

If it can't read then how will it be trained? Talking to it,
perhaps? Feeding it factoids a la Cyc?

Do what humans do, rationalize after the fact a plausible
explanation for how the conclusion was arrived at. :-)
