@hypolite If you don't like the magnetron example, I'll give a super glue example. Super glue was designed to seal off open wounds in the battlefield, to replace stitches. It turns out the toxicity made it bad for what it was designed for. But it was discovered that it was great for gluing housohold items.. a purpose that it wasn't designed for. We don't reject Super Glue simply because it's not being used for what it was designed.
