For context I've been an AI skeptic and am trying as hard as I can to continue to be.
I honestly think we've moved the goalposts. I'm saying this because, for the longest time, I thought that the chasm that AI couldn't cross was generality. By which I mean that you'd train a system, and it would work in that specific setting, and then you'd tweak just about anything at all, and it would fall over. Basically no AI technique truly generalized for the longest time. The new LLM techniques fall over in their own particular ways too, but it's increasingly difficult for even skeptics like me to deny that they provide meaningful value at least some of the time. And largely that's because they generalize so much better than previous systems (though not perfectly).
I've been playing with various models, as well as watching other team members do so. And I've seen Claude identify data races that have sat in our code base for nearly a decade, given a combination of a stack trace, access to the code, and a handful of human-written paragraphs about what the code is doing overall.
This isn't just a matter of adding harnesses. The fields of program analysis and program synthesis are old as dirt, and probably thousands of CS PhD have cut their teeth of trying to solve them. All of those systems had harnesses but they weren't nearly as effective, as general, and as broad as what current frontier LLMs can do. And on top of it all we're driving LLMs with inherently fuzzy natural language, which by definition requires high generality to avoid falling over simply due to the stochastic nature of how humans write prompts.
Now, I agree vehemently with the superficial point that LLMs are "just" text generators. But I think it's also increasingly missing the point given the empirical capabilities that the models clearly have. The real lesson of LLMs is not that they're somehow not text generators, it's that we as a species have somehow encoded intelligence into human language. And along with the new training regimes we've only just discovered how to unlock that.
