Yeah the issue is that you're never going to spend money through a voice interface, which is I think what they were hoping.

The other big issue is that it's not smart enough for any random request to work, so you just learn a few useful ones (timers, music, thermostat maybe...) and stick with those.

I think things might change when/if they hook up ChatGPT-level AI to them... but I still wouldn't spend money that way.
