Because there's no known path to AI and articles like this are pretty much science fiction. Reminds me of that Georges Melies film about going to the moon in a cannon. We didn't have any ideas regarding rockets yet, so cannons it is.

I suspect someone will get some level of mega-expert system/simulated intelligence going sooner than later. Maybe something that can handle the types of commands you could give a dog and it being able to use enough fuzzy logic to work basic things out like, "Get me a coke from the fridge and then get my slippers."

That seems a lot more likely than suddenly birthing human-level AI from NN's. I think NN's will ultimately fail the same way planes work nothing like birds. Trying to copy a biological system very closely just doesn't make sense, at least most of the time.
