Start working with AI
I was talking to few of my friends recently and they were worried about the usage of AI in the workplace specially Co-Pilot. It’s a new tech and even developers are hesitant in using it, and their fear could be genuine, some said it will take away their creativity few doubted it will reduce their analytical ability in longer run. I have a different perspective, you need to adapt to change and use it for your benefit, write code yourself first, then validate with AI, see what was changed and why. Now, adapt to the improved style of coding, do not buy everything from AI unless you understand it. Use it for your benefit as an “Assistant”, not as a “Master”.

I have mentioned some basic points for engineers/developers on where and how they can start. Its upto your creativity to identify on how and where you need assistance.
GitHub Copilot is an AI-powered coding assistant developed by GitHub and OpenAI that enhances productivity across various software development roles by providing real-time code suggestions, autocompletion, and natural language-based assistance. It integrates into popular IDEs like Visual Studio Code, IntelliJ IDEA, and JetBrains, supporting languages such as Java, Python, JavaScript, and more. Below, I’ll outline how software engineers, including Java/Python developers, mainframe developers, cloud developers, testers, and business analysts, can start using Copilot, when and for what purposes it’s most effective, and provide practical examples of its usage.
