I use pencils, pens, inks, chalk, brushes and paint. I prefer them to digital tools. Many old & young artists do. In fact, that F5O logo I posted was scanned/digitized from super clean pencils. As a result of being good with the trads, the modern tools did the rest of the work in minutes. You gotta get out more.
I only sketch thing out, and scan them in the computer. Haven't used tradition illustration tools, since the early 80's. When I was cleaning out my office, I found a couple of my old air brushes. I still know a lot of fine artist, where I worked that still paint, and illustrate conventional. It ends up digital. A lot of my friend out side work still paint, and have their work in galleries.
While I love drawing boats in the 'puter, and being able to render the 3D in minutes, I also love laying a clean sheet of paper on the drawing board and sharpening my pencil. There is NO better way to create a perfect line than using a bendy piece of wood and some lead weights. (Google splines and ducks sometime)
Pencil? Yes, using a plastic "lead" for solid black lines. ****, it's fun being old.
