Um, why? A "handset like device"? So, it's like a phone, but isn't? Even if it is a phone, why? What could it possibly offer that having your "favorite" LLM installed on your real phone wouldn't? Always on spying on everything all the time? Not sure many people are signing up for that. And you can be sure if this is SpaceX it'll have Grok, which is (IMHO) the shittiest choice in a very competitive field.
#Musk says this is fake. Musk is a liar, so... could go either way.
