Amazon Echo gadgets are doing 'witch-like' laughs and refusing to obey

Remember that bit in 2001: A Space Odyssey when the computer turns evil and purrs, 'I'm sorry Dave, I'm afraid I can't do that'? We may have reached that moment with Amazon's now-ubiquitous Echo devices, which seem to be emitting'evil' and'witch-like' laughs and refusing to obey their masters. One user claims that Alexa refused to turn the lights in his house off, repeatedly turning them on with an'evil laugh' So is it time to unplug the devices and shove them into a toaster before they turn on us and murder us all in our sleep? Lying in bed about to fall asleep when Alexa on my Amazon Echo Dot lets out a very loud and creepy laugh… there's a good chance I get murdered tonight. Amazon's Alexa is supposed to laugh when you tell it a joke – but users are reporting that the devices are laughing at inappropriate moments.
