I have a speech recognition standing fan with touch button. Its terrible. The voice is loud, the touch controls dont register very well, give me a dumb thing with physical buttons please!
How do you know that your dryer won't lock onto an open wifi? How do you know that your smart TV won't download malware? You don't.
Contrarily, if you accept that you only hear the dryer "DONE!" bell if you are within 20' or so, you can be certain that the dryer is yours and yours alone.
