I don't think that the alzheimers consensus is the amyloid beta hypothesis anymore where it's one protein going rogue. Otherwise interesting article, though I disagree with this idea that its "less" like scissors and "more" like malware. They pretty much are molecular scissors, but they're definitely not malware. They're actually the anti-virus system of a bacteria. Calling them malware doesn't make sense as a metaphor (they arent Infcetious etc) and just confuses things more.
