Is Eliza Human?

Trying to program Eliza was rather difficult.  It was challenging to remember each code that you had to use to get Eliza to say certain things.  I would often type in a code but nothing would appear in the 'Your Results' box.  I was unclear as to why the codes that I typed in didn't work.  I looked back at previous levels to make sure I was doing it right, and it seemed that I was doing it correctly.  I didn't find this enjoyable or interesting.  It took way too long for me to learn and do each level of programming.  Eliza doesn't have the communication skills or vocabulary of a human, so it was hard to try to teach her those things.
