I had to laugh out loud about that, I really did. Today's photographers know less,and less,and less. I've been involved with photography for 35 years now,and every year I see people who understand fewer and fewer fundamentals.
Like, how to compare flash power in Guide Number, or how to compute a flash exposure using guide number: just last week, Strobist group leader Village Idiot tried to tell me that a cheap $99
Adorama Flash Point 320 monolight MUST be vastly more powerful than a $420 Canon 580 EX-II flash, even though with equal beam spread both units have a flash Guide Number of 118, in Feet, at ISO 100. Village Idiot tried to tell me, no, he tried to "school" me in open forum, by telling me that the Guide Number of the Canon speedlight was "58". Hah! The Guide Number is 58 in Meters, with the flash head zoomed to 105mm, which translates to 190 in Feet. Oh, yeah, today's photographers, "know more about photography now than ever". Uh, apparently not. After trying to 'correct' my comment about flash power of a Canon 580 flash in one post, the V-I in a second post in the same thread, tried again to "school" me by claiming a 150 watt-second,cheap, monolight and what he called a 50-watt-second Canon speedlight could in no way be comparable in flash output--but using a car analogy! Unfortunately, he's a Strobist member, a group leader, and yet he didn't understand the concepts of Guide Number in Meters, and Guide Number in Feet, nor the concept of stored energy, which in the USA is measured in watt-seconds, but which tells us nothing about the actual Guide Number--ie the "actual flash power output" of the flash.
Let me explain our young, 20-something Strobist group leader's line of thought, as he tried to correct me with his eroneous understanding and knowledge. His position was, in effect, "MY boat's fuel tank holds 150 gallons of fuel, and your boat's fuel tank holds 50 gallons of fuel---therefore my boat is three times faster and more powerful than your boat." That's the argument a young photog of today tried to "school" me with.
Today's photographer's rely more on automation than ever before. Many know nothing about depth of field, and do not even know how to read a depth of field scale. Who here can establish a 3:1 lighting ratio, either with a light meter, or by positioning two lights by distance? Who here understands why fill light is usually placed on-axis? Who here can describe how to focus a 50mm lens at its hyperfocal distance? Use the depth of field preview much? Know how to figure out how high a flash must be to avoid redeye at 10 feet? Know how to use an extension tube? Know how much light a 1.4x teleconverter loses? Know what filter to use with B&W film for dark skies?
No, sorry dude, but 35 years around photography have shown me that on average, today's "photogs" know less and less and less about "photography" than at any time than in my lifetime. There's a difference between knowing how to catch a fish, gut a fish,then fillet a fish, and cook a fish--and going to a restaurant and pointing at the menu and having a fish dinner appear on your table 10 minutes later. Photography used to require real skill and knowledge...today, combing thru EXIF data to "find out what works" still isn't working, because I constantly see people calling themselves professional photographers, yet shooting horizontal portraits of standing subjects, over-vignetting images, blowing flash exposures, and using fill lights improperly, not knowing that a Fong Dong is useless outdoors, and not even understanding how their cameras work!
Oh,yeah, EXIF information--that is one of the most hilarious examples of a person who has no training in any photographic fundamentals, talking about how great it is to be able to see what shutter speed and aperture the CAMERA SELECTED in Programmed mode.
"Today's photogs know more about photography now than ever!"

That made my day. There's an old saying, "You don't even know what you don't know." And THAT is the way I view many of today's digital photography practitioners--totally,totally lost without the aid of an automated camera and automatic light metering. Unable to answer even the most fundamental technical questions, simply because things are so,so easy now.
Today's photogs who grew up with the internet beg to see EXIF information, thinking that knowing an f/stop and a shutter speed will unlock the mysteries of photography. I see it all the time on photo forums; "Where's the EXIF information?" "What did you do with the EXIF info!!" It makes me amused to think there's a young guy here telling us that today's photogs know more about photography than ever before. I'm sure he buys much of his food frozen in bags and frozen in boxes, and since many homes have a microwave AND a conventional oven that, "Today's cooks know more about cooking than EVER before!"
"Today's students know more about mathematics today than EVER before--- because they own calculators!"
