Grandmas aren't especially well-known for their razor sharp opsec skills..

That needs to change as much as anything else. We have to adapt, too. This can't be a unilateral thing. We need to change in response to the world around us, and if we don't, we won't survive.

Shifting the responsibility to stay safe from complex attacks to the user will never work for a tech company, even one with the resources available to Google. If Google Assistant is a reliable way of scamming grandmas it will fail because there'll be constant negative news about it in the press.

Oh, what was it... I'm sure I wrote it down in my Google Keep somewhere.
