EXANTE CTO Richard Forss reflects on the dot-com crash, past AI hype cycles, and the real impact of modern coding assistants. Drawing parallels with radiology and DeepMind’s protein-folding breakthrough, he argues that AI can make technical work faster without eliminating the need for human expertise. The deeper lesson is that software engineers were never hired simply to write code. Their job is to solve problems, and AI gives them more opportunities to do so.

AI models from OpenAI and Google helped researchers find PHP2Shell, two critical PHP flaws that let attackers take over servers with no login. PHP runs about 70% of websites, so WordPress, Drupal and Magento sites on unpatched PHP are all exposed. The NSA says patch to 8.5.12, 8.4.27, 8.3.36 or 8.2.35 now, or take systems offline.

Choosing between asyncio and multiprocessing starts with identifying your bottleneck. Asyncio improves throughput for I/O-bound workloads by letting tasks share an event loop while waiting for network or database responses. Multiprocessing runs CPU-intensive work across separate processes, bypassing the traditional CPython GIL constraint. This guide explains when to use each approach, how threads fit into the picture, and which production anti-patterns can undermine performance.

Choosing the right Kubernetes serving stack depends on your workload. Use vLLM or SGLang for LLM inference, KServe, llm-d, or NVIDIA Dynamo for serving platforms, and KEDA or Knative for autoscaling. For fleets of small models, SIE simplifies deployment, routing, and GPU utilization. Match each layer to your workload instead of trying to find one tool that does everything.
