The letter reads as follows:

Sent on behalf of TED KACZYNSKI
to

POLAND
June 12, 2018
Dear Mr. [redacted],
I could not possibly supervise your [redacted] paper, because I would not have time, and in any case my postal communications with Europe are much too slow.
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 Mathematics will probably be the first field in which human intelligence will be totally superseded by machine intelligence, so that human mathematicians will become superfluous.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 is likely to 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 Kurzweil, The Singularity is Near, and Martin Rees, Our Final Century, also published under the title, Our Final Hour.
Yours,
Viveka [signed]
On behalf of Ted Kaczynski
