These days, I can use Codex to get through electromagnetics research in a day that would’ve taken me months before. Electromagnetics science is very mathematical and incredibly painful to code and test manually, with some physical concepts that are genuinely difficult to understand. Normally, it takes humans about a decade of training to become solid experts. For AI, much of this physics, math, and coding seems to come naturally. GPT now allows me to test ideas I never thought I’d be able to test, simply because I couldn’t afford to spend weeks or months on them. And it feels like magic. And I imagine it’s similar across many other fields. This is why I don’t spend much time arguing with AI doomers who think it won’t generate positive returns. While they debate whether AI will create value, people using it for meaningful work are already seeing it.
