Instead, we've spent that time doing things that are only going to exacerbate the issues - like doubling down on voice as an ID

More importantly, trust in both public and private institutions and even between citizens has slowly eroded - understandably so, if you ask me, but still - which as another commenter has pointed out is going to be even more important going forward. I imagine rebuilding that trust is going to be even more painful with stuff like this.

(The only other alternative I can think of is along the lines of cryptographically-signed content from end-to-end, government ID to access the Internet, etc. This would be highly detrimental to a free society, so I hope we don't go this route)
