WHOA. Talk about burying the lede... Look from the beginning of the slide show, he made a super cool geothermal project! Look at the size of this hole!! https://perl.petamem.com/gpw2026/perl-mit-ai-gpw2026.html#/1... His cad drawings are great too!

Basically he wanted home automation in Perl to control his geothermal/solar house, and ended up reimplementing Perl with AI. That's some yak shaving...
