I try to go to various "machine learning" and "AI" meetups around my city.
The most frustrating, but relevant, lesson I've learnt is to just stay away from everything IBM/Watson.
I can summarise every single bloody presentation they give because it's the following:
"Now, when we say cognitive computing, we don't mean any of that sci-fi and AI stuff, now here's a marketer and marketing materials that will explicitly imply that we're talking about that sci-fi and AI stuff for the next 59 minutes. There will be no technical information."
