I took essentially no photos in my twenties (long before phone cameras) for exactly this reason - and, in the short term, absolutely did remember events better than the folks who were constantly looking for their next digicam shot. I'm now living the long-term of that, though, and regret that I have nothing "tangible" to show my wife and kid, or even to re-spark my own memory, about all the amazing things I did back then.

I'm a bit more intentional now: I don't pull out my (phone) camera all that often, but I try to look for something that will represent - not record (that's impossible), but spark a memory of - the moment later. By the way, people are more important for this than things, or "the thing" itself. I actually think the selfie brigade are on the right track, for all that they may become annoying by overdoing it.
