I can still dodge those by disabling Location Services and using something else than Google app-wise.
It is not clear how opt-out this will be. Even if it can be disabled today it might become pushed harder as time goes.
You can disable this too: Home Settings > Suggestions
I believe the computation is done fully locally, as for "tracking", every single OS has a history of what applications you've launched recently, how is that any different?
A lot of those words are from the commenter, not sure where they pulled it from. The article says:
> Actions take advantage of machine learning to surface your app to the user at just the right time, based on your app's semantic intents and the user's context.
"Semantic intents" are basically Android intents. So yes, it's more than just what app you are in, but rather which window of the app you are in. There is also user context, which is things like what time it is or what other apps you have opened.
All this is fed to a model that basically practice, given the current context, what other intents you may need. It's nothing really out of the ordinary.
The commenter tries to imply it that it tracks every input, which is unfounded.
