The challenge is how do we make it economically viable for both the producer of the technology and the end user to keep it useful and local, while also making it a good user experience?

The thing about cloud-based services is that they leverage scale well, making many things cheaper than they ever could be locally unless you buy a device and use it for long time AND fixes can be rolled out quickly with no lagging install base to cause problems or bad user experiences.

I really do want to have my privacy and keep my data safe but I also recognize that's hard to do without higher cost or more hassle (or both).
