It's a lot.
@timrichards It means that I can voice dictate a Captain's Log, like on star trek, by saying "Siri, Captain's Log".
It's not as elegant as depicted on TV, due to input processing limitations, but it does work. And it's powered by Siri thanks to Siri Shortcuts.
So the assistants aren't necessarily as useless/inflexible as they might seem, is my core point.
@timrichards everything that Siri can do adequately could be done using the Pre-Siri Voice Command feature.
Apple have removed this functionality from history, but I was more successful playing a specific song from my music library on my iPhone 4 than I have on any iPhone since.
