I often wonder about the threat from the artificially unintelligent.
I've seen a articles on runaway bots and IoT blunders, no SciFi stories I can think of.
Maybe AI will get us someday, I am just thankful for all those great stories.
On an unrelated note....I recently read that a TV series based on the Foundation Trilogy for HBO is in the works. I am so happy it's finally happening and that it will be a series instead of a film.
