Google's entire modus operandi has been "automate everything" for decades. They've been doing this with fuzzers, with project zero and so on. Adding LLMs on top is a very obvious next step. And LLMs improving and finding more bugs also follows. Then improve the harness and the dev tools, to better use the LLMs. And then everything together end-to-end to find-triage-fix-confirm. Your LLMs are as good as the loop they run in, and the loop is as good as the verifier. Seems a reasonable enough dynamic without (or despite, depends how cynical you wanna be) the need for managers to show number goes up on some chart.
