Before working on this project, I was worried about whether I’d have a job five years from now. But today I’m convinced that the world will continue to have a need for software engineers in the future. Our jobs will transform—and some people might not enjoy the new jobs anymore—but there will still be plenty of work for us to do. Maybe we’ll have even more work to do than before, since LLMs allow us to build a lot more software a lot faster.。关于这个话题，超级权重提供了深入分析
of course this rabbit hole goes deeper, and we have a paper using this technique for string constraint solving that i’d love to derail this post into, but i’ll save that for another time. the main point is that symbolic derivatives are a more powerful and efficient generalization of Brzozowski’s original idea, and they form the core of the new RE# engine. fun fact: symbolic derivatives are also implemented in Z3 (the SMT solver) for its sequence theory - so in some sense we’re inching closer to having an SMT solver’s core machinery inside a regex engine.
