Very impressed that OP has gone from starting university in 2021 to becoming a Senior Security Engineer.
It's an incredibly exciting time in security research in my humble old man opinion.
Think the cadence of new exploits is perhaps a good measure of that rather than subjective thoughts by anyone regardless of experience.
Okay, but none of that is actually responsive to what the article is discussing, which is competitive CTFs. There's not a single criticism of using AI for actual security research in anything they wrote and they mention being a heavy user of GPT-5.5 and GPT-5.5 Pro so belittling the author's experience to defend LLMs wasn't actually necessary.
