Take this with a grain of salt since I’m neither an engineer nor a computer scientist, but have you taken ANY programming? I’d take an online course on Python. Code Academy is a reasonable example. It will give you a taste. You don’t need advanced courses to know whether you could envision sitting in front of a screen hammering out code day in and day out. As for pay, a high paying job you hate isn’t sustainable. Choose the one you like best. Both will pay well. Lastly, a minor isn’t necessary, especially in CS. You can take a few classes or even learn on your own. The final proof is in your ability to code, not the paper you carry. Good luck.
