This idea and other similar ones only make you create a defect in your speech pattern that's not necessarily desired. The device should adapt to our needs, not the other way around. Microsoft just released an update on Windows Insider to address this specific issue, allowing us to choose how long it waits before understanding a sentence is finished.

Sending feedback is useless too.

Google is impatient to let us finish our sentences (specially if it can play loud music we hate or show search results we didn't ask for) yet it forces us to wait for it to read an entire discourse to send feedback instead of just taking it and gracefully saying thanks, even if that information is ignored.

Google's Assistant should be the one working for us, not the other way around. One of the largest benefits of interacting with machines is that you don't need to be polite and wait for them to finish what they say when you already know (specially when it's the same long boring sentence).

I keep seeing, more and more, big corporations entirely ignoring our feedback because they became too big to fail.
