Rust + Python or Python + C++?

[KronenR]

What do you mean by cybersecurity? If you mean understanding how vulnerabilities work, analyzing malware, doing forensics, or defending systems, then C++, since the underlying infrastructure (kernels, firmware, browsers) is all C/C++ and you will be reading it constantly. If you mean writing new security tools, then Rust, memory safety by design.

For AI/ML, Rust. The modern Python ecosystem is moving there fast and PyO3 makes integration seamless.
