"Let's give them an uninterruptible wireless connection to a central robot leader. A 'general,' if you will."
The plot kicks off with the apparent suicide of Dr. Lanning, a doctor of robot-making. Before he "fell" out a window, he set up a hologram of himself that would automatically call Will Smith in the event of his death. It's an incredible interactive program that can a multitude of questions Smith's character is anticipated to ask. Well, sort of. It has extremely limited responses, and never tells Smith anything with any practical use. It hints at a "revolution," but not who will start it. When asked why Dr. Lanning would commit suicide, it coyly suggests that's "the right question," but offers no real answers. It's so vague and cute that it almost seems like it was designed for romantic scavenger hunts, not for future investigators to investigate your death. Why even make it? Just leave a note that says "THE ROBOTS ARE REBELLING, SO IF I COMMIT SUICIDE, I PROBABLY DIDN'T."

"Why are you so damn useless?"
"That, Detective, is the right question. Go to the SAUCY place where we first ca-NOODLED to BITE into the next clue!"
Sure, the hologram obviously utilizes some advanced technology, but all of its basic requirements could be fulfilled by a voicemail. The doctor wanted Will to investigate the robots and discover their evil intentions, but why turn that into a series of word puzzles? Wouldn't most robot-hating detectives be perfectly willing to look into an uprising of terrorist murderbots without a hologram of a dead guy winking at them and leading them toward a fun mystery?
