"profile view challenge" coming in 3, 2, 1 ...

It's probably not obvious to many that there's nearly a limitless source of training data on social media at this point. Your comment is eerily prescient and now all trends can become suspect as being a plant for additional training to circumvent, well, known circumventions!

Tangentially related but a simple way to bust a chatbot is to ask “What is larger, the Eiffel Tower or a shoe box?”

I think you're on to something. The modern day chat-bot/answer engines seem very susceptible towards trying to answer fact-based, yet obviously incorrect questions. They seem unable to parse the entire question and instead focus on the most generic terms. For instance, the "What year did Neil Armstrong land on Mars?" example that shows up on HN from time to time.

I remember someone posting a chat thread from one of the more advanced AIs within the last few years wherein they asked it who the president of the US is, and it was not able to answer. Interestingly, this is a question my father would ask patients as a paramedic who was trying to assess people's consciousness. Another would be, "what day of the week is it?". I'd say that these technologies are just like magic - they…

Depending where the bot is and what time of day it is, it might tell you the wrong day of the week.

I wonder how much work would it entail to swap one actor's face for another's in a movie. Just finished watching Fury Road, and Tom Hardy just feels a bit off to me.

That's "bread and butter" work in VFX. I used to be a stunt double actor replacement specialist. These daze, ML enhanced tools make the work for a face replacement shot exponentially faster and easier - as is needed for the huge number of superhero stunts insurance companies will not let the stars perform.
