for those of you who have clients who are concerned with privacy, note that you have to go into system prefs in your mac and dig into the "siri suggestions and privacy" and shut off sirl for all the apps listed there, if in fact you don't want siri scanning your data. it is not enough to shut off "enable ask siri" at the top level. i found this out when siri scanned open safari pages and wanted to add things to my calendar. what? apple must have hired some google employees, heh.
