I'll pile on a prediction, this is what finally introduces centralized computing into the home the same way we have central air conditioners.

You can put in a frame or rack, install blades as needed, modular as lightbulbs.

Devices can be just screens and batteries with the video being piped down over existing Wifi or whenever, I have 6E at my home and it connects at 2.4Gbps - runs Parsec perfectly.

Your home core will run your AI with whatever hw modules you can stuff into it, and it is charged with protecting your information, it knows how to expand itself if you can provide it more compute.

For workloads the AI needs to outsource, services will agree to legally guarantee that when their AI is given access to your private copy of an S3 bucket of relevant personal information that it will provide an answer and will keep none of your data - only keeping the solution steps to help other users.

Users in local nets can offer spare encrypted containerized capacity that your neighbor's AI can rent for a nominal automated fee, likely paid for by selling some solar credits back to the grid automatically, lowering the load on centralized servers - to run a data set and return with the answer and shut down the container and wipe it - or return logs to the originators system.

When you pull the people out, you remove the temptation of user indiscretion, when it comes to things like legal contracts and business dealings believe me you want the most dispassionate law-abiding robot you can get.

Just watch out for the ones they give guns, because that's one of those times where that human discretion can go both positive or negative depending upon the situation.
