I think the main impact of this is that a successful career in vulnerability research is going to require a high level of proficiency in exploit development, as that's where the demonstrable real-world impact lies.
Tech careers no longer exist. Tech jobs will still exist for a few years, but careers they will no longer be.
Honestly, even that is something LLMs are becoming scarily good at. Not all of it, but they have surprised me, including in terms of exploit development, more than I am comfortable with.
