I'm all for increasing education on this, and I do think that would have some value, though I'm not 100% sure what this would look like. My mother-in-law's husband has fallen for these gift card scams multiple times, losing thousands of dollars, even after I've tried showing him some obvious and less-obvious warning signs [1]. Some people are just really gullible, for whatever reason, and I'm not 100% sure that education will actually help them.
I actually don't think we disagree very much about the actual solution to the problem. This is definitely bigger than a few Youtubers making scambaiting videos. It's going to be a brave new world with AI voices getting better and better, and I think law enforcement agencies are going to be pretty proactive.
[1] e.g. the IRS will never ask for payments in gift cards or cryptocurrency, neither will the police, don't just let anyone connect to your computer with Teamviewer or Anydesk, if you're going to be arrested they probably aren't going to do it over the phone, etc.
