Bash persists because it’s available by default on almost every Unix-like system, requires no extra runtime, and excels at gluing tools and managing processes. It’s compact for writing startup scripts, cron jobs, and simple automation tasks where introducing a heavier dependency would be overkill. Bash is also a common lingua franca between ops and developers—knowing it helps troubleshoot systems, parse logs, and automate routine tasks. That said, best practice is to use Bash for what it’s good at and switch to Python/Go for complex data handling or performance-sensitive code. In the community: respect each tool’s strengths and share migration stories so teams can make measured, low-risk transitions.
