Oh I obviously know that this kind of thing is already achievable, but it's the barrier to entry is getting substantially lower... Instead of needing a nation state actor that's got funding and resources behind them, we're getting close to the point that some degenerate kid in their bedroom could say "hey claude find me the api keys and services behind nasdaq and build me an interface that spoofs transactions to XYZ". Or send commands to traffic light controllers. Or every third transaction from XYZ bank on every second day has one cent transferred to this other account.

Not just api calls but the business logic too.

Laymens thoughts there, but in essence this is my concern. People just looking at any old service in the world and going "hey claude build me a hook into this" and the models are getting close enough to being able to find and decompile the right moving parts on its own.
