Where to start...
I drove to work this morning in a car with carburetors, points ignition, and a manual transmission. Even though
@D.T. makes a good case for ICEs being an "ongoing" technology, I could point out a dozen reasons easily why the one in this car is ancient technology

.
I will write today with a fountain pen-or probably a couple of different ones. My main one was made in the 1960s(Mont Blanc 22) but I have some back to the 1930s in my desk(including my prize Sheaffer balance), a relatively new pen that's been in continuous production since the 1960s(Lamy 2000) but that I bought new a few years ago, and some that are recent designs. Still, they're not exactly dominant technology.
If the weather holds, I might go out and take some photographs on film. Depending on how the light looks, I might use a Nikon F100(1999), Nikon F2sb(1975), Nikon F2AS(1977) Hasselblad 500C(1960), or Speed Graphic(1950). Of course, I'll be using them with fresh film. Also, I'll probably use the F100 with relatively new lenses, although the F2s will get older ones. Depending on what I'm doing on the Speed Graphic, my lenses range from the 1930s to the 1990s. 4x5 film dates to the beginning of plastic-backed cut film(I think the 1910s), although I do have some glass plates also if I want to be adventurous(I want to shoot color, so that won't happen). 120 film was an early Kodak roll film size, and it just happened to be the only one that survived to today thanks to companies like F&H(Rolleiflex) and Hasselblad adopting it-and then it becoming the defacto "medium format" film size due to momentum from those others adopting it. 35mm film dates to whenever Oscar Barnack decided that he wanted to use motion picture film in a small camera that was easy for him to carry when he was climbing mountains. I mostly shoot Fuji Velvia, which came out in ~1989, and Kodak Tri-X, which dates from the 1950s. Both have been tweaked and reformulated-most recently 2006 for Velvia 50(after the original ASA 50 Velvia was discontinued for environmental reasons) and 2008 for Tri-X.
Oh, if I mount the cameras on a tripod, it will be a Marchioni Brothers Tiltall-a design from the 1930s and produced by them until I think about 1960(Leitz after that, and still in production today).
When I go to the range, I mostly shoot revolvers including ones patterned after the Colt single action(1873) and ones patterned after the Smith and Wesson model of 1902/1905. I even have an S&W model of 1899 in 32-20, another ancient cartridge. Most of my handloading is done with Unique powder, which claims to be the oldest commercial smokeless powder still in production(1899) or its slightly younger and faster brother Bullseye(1902).
