>>503>have the thinking done on a server with it puppeting your robo-meido,
Yes, anon. I think that's more or less the idea. Have an in-home server setup designed and built for heavy processing, connect your robowaifu into it wirelessly (and securely!), and just offload the bulk of the computation onto the server. This would add a bit of complexity into the final solution, but not much.
The robowaifu's systems will necessarily be so complex in general, that a modest redistribution of the computing load will be only a relatively minor detail in the overall scheme of things.
