Mathematicians are happy to use computers for typesetting papers, but not for the initial creative phase: 1) computer displays require you to scroll, which interrupts your mental flow 2) paper and pencil or pen is free-form 3) in advanced mathematics, results are rarely calculated in numerical form, so the computer isn't helpful 4) notebooks are permanent. No backups needed. I imagine the same is true for most cartoon artists.
