> By making these fake images ubiquitous we are forcing people to quickly learn
That's quite the high opinion on the self-improvement ability of your Average Joe. This kind of behavior only comes with an awareness, previously learned, and an alertness of mind. You need the population at large to be able to do this. How if not, say, teaching this at schools and waiting for the next generation to reach adulthood, would you expect this to happen?
I agree that improvement for the Average Joe will be very hard. I also think that taking more attention to teach the younger generation is vitally important. But mostly I don't see an alternative. I don't think we can protect people from fake information without giving up our freedom, and that isn't a viable alternative in my mind. So what is left but trying our hardest to teach people to think critically?
