I disagree, firstly with the idea that you're not a photographer - you take photographs and have a very active interest in doing so. Your photographs are considered and intentional. You're a photographer.
Secondly, how does one surpass another in photography?
Regarding the link: some great photographs, undoubtedly, but almost no black and white, or street photographs, and surely some of those must be among the 100 Best Photographs taken without Photoshop?
And this sort of leads to what Somebloke said and the OP agreed with; most famous Black and White photographs had work done in the darkroom to enhance the photograph. There was a link posted here maybe a year ago about the darkroom technician at Magnum and the work he did on some of their most famous photographs - dodging and burning mostly - and the difference it made to the final image (the one we know) compared to the negative (still the same photograph but with a bit less visual impact). Enhancing but not manipulating ... and definitely not Photoshop, due to it being done manually by a man in a darkroom.
That said, both retouching and composite images existed long before Photoshop as well. There was the example of Ansel Adams touching out some graffiti from a landscape. That's manipulation of the scene, right? Not Photoshop (which has become a synonym for image manipulation, it seems) though.
As usual, I don't even know what I'm saying anymore. Peace out!
EDIT: I'm also fairly sure I've missed the point, at least of the link.
The photographs there show various important parts of photographic practice. Understanding of light, colour, exposure. Great composition and timing. Choosing your subject and seeking it out; going to whatever lengths necessary to photograph it. ("If you want to take more interesting pictures, stand in front of more interesting things.") Getting yourself into the right position, at the right time, to take an amazing photograph.
None of these things rely on either a darkroom or a computer ... some of them did require a helicopter, though. But even if we don't have a helicopter (I don't even have a car) we can still push ourselves to get up for the sunrise; hike up that mountain; or get out into the streets and push ourselves to take photos.
