“A Muggle security expert would have called it fence-post security, like building a fence-post over a hundred metres high in the middle of the desert. Only a very obliging attacker would try to climb the fence-post. Anyone sensible would just walk around the fence-post, and making the fence-post even higher wouldn’t stop that.” —HPMOR, Ch. 115

This is actually one of the major reasons why 80k recommended information security as one of their top career areas; the other top career areas have pretty heavy switching costs and serious drawbacks if you end up not being a good fit e.g. alignment research, biosecurity, and public policy.
Cybersecurity jobs, on the other hand, are still booming, and depending on how security automation and prompt engineering goes, the net jobs lost by AI is probably way lower than other industries e.g. because more eyeballs might offer perception and processing power that supplement or augment LLMs for a long time, and more warm bodies means more attackers which means more defenders.
