Assistants, yes; AI I think NOT!

Interesting stuff as usual for Nova, but the conclusion is we have a long

that long and have sounded the AI alarm that AI may destroy us.

Do check out the TrueNorth chip (mentioned in the video) developed by IBM
c. 2014. The chip integrates memory and CPU to mimic neurons and synapses:
