when did you clean this last?

They would build a new machine standing next to HEX and HEX would be... not jealous, of course, why would you think a machine would be jealous? But still HEX would randomly start responding to someone who would spend more time with that new machine.

I'm 100% positive that Dibbler would be mass-printing generated bad romance novels and selling them for profit. All of them would have titles like "A Necklace of Pearls and Flowers" or "A Menace of Dragons and Swords", depending on the audience.

People would buy dis-organisers with new features and the imps would give VASTLY inaccurate answers ("No, dragons don't breathe fire, this is a myth, you are safe!") that would put them in danger - and yet would still refuse to get rid of them. (Maybe Dibbler would sell those advanced dis-organisers, too, sounds like something for him.)

The Watch would have their hands full saving people from said danger. Vimes would never trust this new invention and would get extremely angry at anyone suggesting he bought one, too.

Dwarves would be very anxious because, as our dear Blackboard Monitor already knows, Words Are Important. And if those words come from gods know where, that's really bad. I can actually see the plot where they can actually team up with Blackboard Monitor to destroy those "machine" words at the end.
