In the landscape of 2025, Python remains the dominant force in data science, backend systems, and AI orchestration. However, as our applications scale into complex microservices architectures and process terabytes of data in real-time, the “unlimited RAM” mindset of the early 2010s is no longer viable. Cloud costs are scrutinized, and Kubernetes pods are ruthlessly terminated when they exceed memory limits (OOMKilled).

In the landscape of 2025, Python remains the dominant language for data engineering, AI orchestration, and backend web services. With the maturation of the No-GIL CPython (introduced experimentally in 3.13 and stabilized in subsequent versions), threading performance has skyrocketed. However, one fundamental constraint remains: Memory.
