Its interesting that in the last 30 years we've gone from unworkable text adventure interfaces to the same unworkable interface in verbal form instead of typed/read text. A lot of his story reads as a parody of an Infocom game but spoken instead of typed.
Echo is cool, it can be pretty useful, but it hasn't realized its full potential yet.
I bought the Tap as a portable speaker to take with me on bike rides with friends. Well I took it out the other day and the minute it lost WiFi connection it just wouldn't work. I'm sure this was a problem on my end, but I had already paired the devices and I wasn't going to spend time fiddling with it while I was out with friends.
EDIT: Also it doesn't happen too often but Alexa has definitely accidentally triggered. It even woke me up at 2 AM after the power went out temporarily to tell me that it had no WiFi.
