In 1988 I was an intern at HP Labs and my project was 50% Lisp and 50% C, the latter half dealing with time-critical IO and low-level routines crunching CAD tablet input.<p>At the end of a day working on the Lisp portion, which assembled sketched lines into a CAD model I went home happy and relaxed with a feeling of accomplishment. At the end of the C days I felt tense and slightly worried, thinking about ways of more cleverly detecting what the user was trying to sketch on the tablet.<p>In my 20+ years of programming I never returned to Lisp and I don&#x27;t quite know why I don&#x27;t miss it. I have a vague nostalgia for Lisp but I think modern programming languages give us enough tools to get our job done without feeling too much shame about abandoning the purity of Lisp.<p>Also, the proselytizing has not helped. I think the &quot;Blub paradox&quot; article embodies the mindset that was ultimately the nail in Lisp&#x27;s coffin.
