Another good question. I don't super understand a lot of the "I downloaded a software, bought a radio, and look it works". But I do like, for example, things like [1]. The reverse engineering side, the legal hacking side, that's where it gets interesting. The Flipper Zero is a great example of that, though I've never used one. Another example I thought of on the industrial side is old NASA equipment like in the curiousmarc series. Any time they change anything, even frequency by a small amount, it involves effort like swapping out crystals and tuning filters and junk. In SDR, it's just a variable.
