If AI could optimize PLC ladder logic in real-time, would we still need human programmers or would they become 'AI whisperers' managing the machine learning algorithms?

That's a really interesting question about the future of PLC programming! Based on what I'm seeing in the industry, it looks like AI is definitely transforming how we work with PLCs, but human programmers aren't going anywhere - their role is just evolving.

Right now, AI tools are being developed for natural language to PLC code conversion, automated HMI screen generation, and error detection/correction. Companies like Siemens, Allen-Bradley, and Schneider are working on these AI assistants that can handle about 80% of routine programming tasks.

But here's the thing - PLC programming involves a lot more than just writing code. There's understanding the physical processes, safety requirements, troubleshooting real-world equipment, and dealing with unexpected situations that AI might not handle well. Industrial automation has zero tolerance for errors that could cause equipment damage or safety hazards.

So yes, I think human programmers will become more like 'AI whisperers' - they'll focus on higher-level tasks like system design, safety validation, troubleshooting complex issues, and managing the AI tools themselves. They'll need to understand both the industrial processes AND how to effectively communicate with and guide the AI systems.

The consensus seems to be that AI will make PLC programmers more efficient and productive, not replace them. You'll probably spend less time on repetitive coding and more time on system optimization, innovation, and managing the human-AI collaboration. It's an exciting evolution rather than a replacement!
