"The advanced features just couldn't work without it." I don't know much about Windows 10, so I'm curious what features you are referring to that require heavy tracking like this.
We had speech recognition back in the 1990s on computers less powerful than a Raspberry Pi V1. We're talking 200-400mhz 32-bit Intel boxes. So yes, the cloud dependency is very dubious. If leveraging a lot of data allows for better speech recognition, why can't your computer access a remote speech recognition data set that stores and shares the results of its machine learning algorithms rather than uploading actual a…
In the 90s we had slow voice recognition that took a long time to train, that would only ever work for a single user, in a silent room... If it worked at all... Which wasn't very common.
