It's a memory from the Citadel, when he wanted to experiment with AI and the human embassy was like, "Ugh, you are going to ruin our reputation with the other species!!" and he was like, "You wanted me to find an advantage humans could have against them, and this is it. They're afraid of AIs, but we can use them!"

He thinks that the problem with the geth was that geth were separate from their creators, but you can make an AI that integrates with you, so there is no boundary between creator and created, and what benefits one benefits both. They won't take the risk.

Just sayin', but Javik told us he learned about a race that had AI implants that took over their host bodies... /eyes Ryder and her AI implant that can control her body

This isn't something no one's ever thought of before.

Then Mom calls! She's still alive! And she has a terminal prognosis. Whoops. And Dad says, "Not on my watch," grimly. ...oh boy.
