Hi snoop.
It really depends on what people learn your bot.
Many people don't use proper sentences so Hal
picks this stuff up, It's like a bad influence.
If you or other people spend the time to train your
Hal child as I say, Then your new bot will become like the people
he/she talks to, Of course you could train your bot and turn off all
learning ability so Hal only uses sentences he was taught by you
and the original sentence functions.
If you go on a quest to find a good brain you'll discover that every
learning type brain is constantly being modified and sometimes changes its original character speech functions.
Learning bots are variable.
none learning bots are static.
Hope this helped.
Jerry.
