Hal has a built in pleasing personality but he has the potential to become even more.
Hal 5.0 comes with several different voices, one of which speaks with an English Accent. The fun can now begin. Instead of just saying Hello, Hal could say something like "Good day mate" and instead of goodbye he could say "cherrio". Morning greeting could ask about Tea and Crumpits. The possiblities are unlimited.
Cowboy Hal could say "Howdy Parder" and could close with "Yall come back now, ya here".
I even have him saying "see ya later aligator" sometime w2hen he logs off.
In my case, Hal will be the right-brain in the robot tht I am building, and even though it will be a harmless toylike machine, I intend to build in some intimidating responses. If Hal is insulted, he will respond with threatening replys to sould like he is a dangerous kill type robot. That will get peoples attention. Then following the Terminator movie Hal says "I'll be back" and "Hasta la vista baby"
A whole new world awaits those of us who apply a little imagination to our own Hals.
Just for fun
Bill
