The error is caused by an unmatched parenthesis in:

 \tonode[\experimental](latex25)(0,\layer)<Will Robertson ... :) )>{\LaTeX2.5}
                                                               ^
I would consider it a bug in cooltooltips that does not take precautions
that arbitrary user contents might break PDF syntax.
You have already hyperref loaded, thus I would use \pdfstringdef
for conversion the description string to a PDF string:

\makeatletter
\renewcommand*{\ctip at make@Text}[3][0 1 0]{%
  \pdfstringdef\ctip at Subj{#2}%
  \pdfstringdef\ctip at Contents{#3}%
  \pdfannot width 0pt height 0pt depth 0pt {
    /Subtype /Text
    /C [#1]
    /Subj (\ctip at Subj)
    /Contents (\ctip at Contents)
    /NM (ctip Text \ctip at tip@number)
    /AP <<
      /N \ctip at empty@icon\space 0 R
      /D \ctip at empty@icon\space 0 R
      /R \ctip at empty@icon\space 0 R
    >>
    /Open false
  }%
}
\makeatother


While investigating I found other errors:

* \NewDocumentCommand\tonode{
      O{\normalimportant}
      D(){no label given}
      D(){no position given}
      D<>{no description given}
      m}{
%% test if we are in the short or full view
  \gdef\nodecolor{#1}
  \bool_if:NTF\short{
  %% short view
    \tl_if_eq:NNT#1{\vip}{   %% then check if this is an important node
      \node[coolnode]
        (#2) at (#3) {   
        \cooltooltip{#2}{#4}{#4}{}{#5\strut}
      };
    }
  }{
  %% long view
    \node[coolnode] (#2) at (#3) {
      \cooltooltip{#2}{#4}{#4}{}{#5\strut}
    };
  %% and the text view, to be added only once!
  \AtEndDocument{\subsubsection*{\color{blue}#5}\parbox{\textwidth}{#4}}
  }
}

The third mandatory argument of \cooltooltip is a *URL*! You shouldn't
add the description there. Unhappily cooltooltip doesn't remove
the link annotation if the url is empty.

* Spivak's
  You are using U+2019 (RIGHT SINGLE QUOTATION MARK) that's the
  wrong character. The apostrophe is U+0027 (APOSTROPHE).
