I currently use qwen 3.8 27b on a system with a couple of RTX 3060s that I bought on ebay for personal coding projects. I've been a firmware engineer professionally for a couple of decades, and I recently wanted to branch into mobile app development. Last year, I bought a book on React to learn cross-platform app dev. But, last month I built this pieced-together system for local AI and have come to the conclusion that I will never need to learn a new programming language again. This lil' bastard does everthing!
And, professionally, my employer pays for a top-tier subscription that's able to code, run command line tools, build and install firmware, and even connect to a logic analyzer and debug data lines.
Yes, "AI bots" can write most of your code, if you're able to clearly explain what's needed in your planning and action prompts. And, beyond that, AI can examine an existing code base, very clearly explain its function, and provide recommendations for refactors and other improvements.
At this point, it hasn't replaced me as an engineer, but it's definitely augmented my abilities it in a way that "paired programming" and other stupid Agile-touchy-feely methodologies never could.
