Educator and musician living in Evanston, Illinois. I wrote some Python books, but you'll probably find me yapping on about bikes, trombones, dogs, and other random stuff here. Currently pursuing a MAT in Secondary Education with the hope of becoming a high school math teacher.

Tech companies are destroying social structures, preventing young people from building romances and steady relations.

Connor Leahy explains spot on how tech companies are acting in a 'wild west' fashion. Getting very rich without taking societal responsibility while leaving a great mess behind.
