Remember when developers just... wrote code? Wild concept, I know. The tweet sarcastically points out how Zuckerberg built Facebook in 2005 without today's trendy tech stack buzzwords that junior devs think are mandatory for any project with more than 3 users. Back then, it was PHP, MySQL, and sheer determination—not Kubernetes clusters managing serverless functions with real-time edge replication while mining Bitcoin on the side. Next time your startup "needs" a microservice architecture to handle 12 users, remember: Facebook served millions with technology that would make modern architects clutch their mechanical keyboards in horror.
