I read Donald Knuth does this. He uses a USB flash drive to transfer data to and from his main book-writing Linux workstation. Air gapping has the added bonus that the constant distraction and breakage risk of never ending app updates and security patches is mitigated. As Knuth is someone from the computing era before even floppies and network cards were a thing, when fast data transfer between sites meant mailing a deck of punch cards or reels of tape, it probably doesn't feel that slow to him. He also essentially quit email on January 1, 1990, after using it since 1975, because it was such a distraction from getting stuff done.

Also, George R. R. Martin uses WordStar 4.0 on a DOS machine:
