I disagree with this. Not only does Echo get things wrong, it is extremely limited on what it can answer. If you word the question just right, and it's something that it was programmed to know about it, it might get it right, but since it doesn't have a screen where it can at least post some info, I often get responses it just doesn't know. A great example is the English Premier League. Siri/Google does great with it and can answer pretty much anything, and at the very least give me a web search. Echo has no idea what the league is, who the teams are, players, etc. It can't even give me a web search. But yes, I can ask what year Mt. Rushmore was finished and it will know, great. All too often it just has no clue.
Using it with my Hue lights is pretty cool. Except that you have to be very precise with your names and memorize how everything is set up because it won't work unless you know the exact wording it wants (and ask it in just the right way). And even then, you can't turn off groups, only turn them on. It will turn off all lights. That is a limitation of all the voice services of course, but I still have to repeat commands a lot with it, and it is very finicky.
Having owned an Echo for almost a year now the thing is basically an alarm clock and bluetooth speaker for podcasts (doesn't sound that great for music when I have other options available). I like it, but the praise it seems to get lately on being better than alternatives boggles my mind.
And since when is Woz relevant on anything?
