bash scripts, famously the last word in software engineering. all these castles of sand we've built atop the beautiful, perfect, timeless Bourne Again SHell. all for naught. fools!
At one point the web was bash scripts glued together. Now everything is brought into a runtime. Then brought into virtualized containers to isolate and hide from every other aspect of the operating system.
Eventually the agents will be on a runtime as well. The existing ones just aren't good enough. Rather than forking like made as a way of doing everything, exfiltration into arbitrary executables will be something more tightly controlled.
Organizations need better in-product control and auditing of the operations of the agent. They need it to work across OSes and not depend on the state of the machine, and not conflict with what else the developer is trying to do with it.
The design of pipes and the philosophy of simple composable tools tied together with the Unix shell has proven remarkably difficult to improve upon.
