a large Java conf, 1998
Rich Hickey is onstage demoing a lisp dev setup
his hacking gets more and more intense. he's jacked into a production server; he starts redefining functions on the fly, inspecting data as it flows thru functions
the audience is shocked and horrified but he continues typing, oblivious. an error occurs and he recovers from it in the repl
finally he sees their stunned silence
"guess you aren't ready for that yet" he responds impishly
"but your kids are gonna love it"
