What does a mainframe developer do?

They work in environments that require high reliability and security, and may also handle system updates, performance tuning, and integration with other systems.

Can mainframe be replaced by AI?

Mainframes are large-scale computing systems used for critical enterprise applications, and while AI can automate certain tasks and improve efficiency, it does not replace the core functions of mainframes. Mainframe developers often work with legacy systems, COBOL programming, and security protocols, which require specialized skills that are not fully replaced by AI technologies.

Is mainframe still in demand?
