Submarines were considered science fiction shortly prior to WWI, and then you got such crazy technological advancements, that battleships were obsolete by the time they were built. Well, submarines weren't science fiction anymore, and were used in unrestricted warfare.

Hope we don't do that with AI. Pretty sure our AGI is going to be similar to that seen in the Alien franchise of films-- it essentially emulates human higher order logic with key distinctions.

It's rapidly turning into science fact, unless you've been living under a rock the last year.
