Huh, I hadn't thought of battery limitations. Good call. My initial reaction is that bigger/better batteries, hyper fast recharge times and more efficient processors might address this issue, but I need to learn more about it.

That said, power consumption is one of the reasons I think pushing this stuff to the edge is the only real path for AI in terms of a business model. It basically spreads the load and passes the cost of power to the end user, rather than trying to figure out how to pay for it at the data center level.
