BOOKS

• Colonel Parker Hitt and William Friedman wrote popular cryptography books in the early 20th century.
• David Khan's book The Codebreaker's told people about cryptography when no information was available.

I wonder ??????
Will coders stop fixing computers and start programming and making robots ????
