Take your example of the ineffectiveness of the note taking defense in support of a dispute. What would it take to overcome that and still retain control of the recording hosting/mechanism? What features would be necessary so that self-recorded records rise to equal authority with corporate records? Will they ever? What about recorded through a 'notary' service offered by a tech giant that you already resign any sense of privacy with?

A hopeful example of the value of self-recording: Car dashcams are relevant for insurance claims. Or are they?
