No, Stackoverflow architecture is still a simple server farm with aggressively maintained code and a lite SQL ORM that lets them to highly optimize queries. One of the architects talked about it on their pod a few weeks ago. She mentioned explicitly how they don't jump on new hotness and keep it classic, maintainable, and highly performant without spending tens of millions of dollars on FAANG alumni who seem to think that every shop needs a Google infrastructure because THIS IS THE WAY.
