I'd really like to have something like this running on hardware I controlled, using open source, because I'd want to load it up with all my personal information with the goal of creating a smart assistant that eventually can be upgraded to full AGI status when the technology becomes available. Unfortunately, what will likely be available in the near future will be a "smart assistant" running in the cloud, using proprietary code, and storing your personal data with truly horrible privacy policies. I'd be willing to pay $$$ for an assistant I can run that will truly protect my privacy.
