Apple already sells a portable, wearable device one can converse with: the Apple Watch. They just need to dramatically improve Siri.

Now, if Humane has some special AI tech that could improve THAT, then they could be worth acquiring.

As is, the Humane pin is just gimmick that's probably going to be brushed aside just as easily as it can be knocked off.

BTW, I noticed in the demo that the woman worn a heavy leather jacket with a lapel stiff enough to support the device.
