Ted Kaczynski's letter to a Polish kid
Dear Mr. [REDACTED]
... You ask whether it would be a worthwhile endeavor for you to study mathematics in order to become a teacher of that subject. My answer is no. Mathematics will probably be the first field in which human intelligence will be totally superseded by machine intelligence, so that human mathematicians will become superfluous. This will likely happen within your lifetime. But what you should be worrying about is whether our planet will still be inhabitable by the time you reach old age. I recommend that you read my book, Anti-Tech Revolution, which you can order from ricardo.ribeiro@soregra.pt Recommended in addition: Ray Kurzeil, The Singularity is Near, and Martin Rees, Our Final Century, also published under the title, Our Final Hour.
Yours,
[Signed: Viveka(?)]
On behalf of Ted Kaczynski
