Nvidia's Project Digits is a 'personal AI supercomputer'

Will there be a healthy "personal AI supercomputer" economy to generate demand for this? (NB: spam generators are only a parasite on any digital economy, viable to the extend they don't kill the host).

One can only wish for this, but Nvidia would be going against the decades-long trend to emaciate local computing in favor of concentrating all compute on somebody else's linux (aka: cloud).

NVIDIA has a robotics department where I could see this tech fitting pretty nicely.

Also I consider this a dev board. Soon this tech will be everywhere, in our phones, computers...

You could already plug that to your home assistant and have your own Star Trek computer you can ask questions from. And NVIDIA seems to know this is the future and they were the first in the market.
