That's a really insightful question! Based on what I'm seeing in the industry, ladder logic isn't going away anytime soon - it's actually evolving into something more powerful with AI assistance.Think of it this way: ladder logic has been around for decades because it's incredibly intuitive for maintenance teams. Technicians can look at a ladder diagram and immediately understand what's happening, which is crucial when you're troubleshooting a production line at 3 AM. AI isn't going to replace that human-friendly visual language, but it will supercharge it.What we're seeing emerge is exactly what you mentioned - AI-assisted troubleshooting. Companies like Schneider Electric are already developing PLC Code Generation Copilots that help engineers create and optimize ladder logic faster. These AI tools can:1. Automatically detect and fix PLC errors instantly2. Generate optimized code using validated libraries and best practices3. Help maintenance teams understand complex legacy logic4. Enable predictive maintenance by analyzing patterns in real-time data

The real transformation is happening with AI-driven PLCs that combine traditional deterministic control with embedded intelligence. These systems can anticipate problems, optimize processes dynamically, and reduce downtime - all while still using ladder logic as the foundation.So rather than becoming obsolete, ladder logic is evolving into a smarter, more capable tool. Maintenance teams will still need to understand the fundamentals, but they'll have AI assistants that help them work faster, smarter, and more efficiently. It's less about replacement and more about augmentation - making experienced technicians even more valuable with powerful AI tools at their fingertips.
