I understand it is not your focus, but fuzzing still falls short and there is a lot AI can help. For example, when there is checksum, fuzzers typically can't progress and it is "solved" by disabling checks when building for fuzzing. AI can just look at the source code doing the checksum and write the code to fill them in, or use its world knowledge to recognize the function is named sha_256 and import Python hashlib, etc.

Hint: we are working on this, and it can easily expand coverage in oss-fuzz even if those targets have been fuzzed for a long time with enormous amount of compute.
