Maybe the term engineer has been watered down from what you learned in school but in my and many other people's views its synonymous with hacker in a lot of these categories. I wouldn't call an electrical engineer an electrical hacker but if you weren't an electrical hacker you'd be a pretty garbage electrical engineer. If you've never messed around with or tested a concept or built a circuit for fun you'd probably hate your job and be worse at it. These people are doing these things with prompting and with software.
