You said it: AI defense against AI, since it is already so pervasive.
Especially so in jobs. AI resume reviews scanning AI-generated resumes.
For years, I wrote down ideas for new and liberating tech applications [0] and services, but found that I was only counteracting the abuse of users by sociopaths in control of large-scale technology.
Each advance is usually snapped up first by military, for more efficient killing, or scoundrels, for more efficient scams, along with some non zero-sum benefits, and it takes time and a lot of effort to undo the damage, though killing is irreversible.
Is there anything we can do?
YES, it's called meeting real needs that aren't fast buck or planetary scale like the "big tech" giants. They go unaddressed, and doesn't a "power to the average person" technology like we dreamt of in the past and never showed, or was dumped, make that possible?
When the first wave of "globalization" came and we all asked "Where are the Jobs" (2004) [1], I thought that FAB would enable people to create bespoke products that met customers' unique needs. Oh well.
Hear me well.
There are many urgent and unmet needs, and we are once again facing a solution in search of a problem, or worse, redefining problems and creating new ones to satisfy the solution.
