Indeed, the name and their use in sci-fi settings trips people up into thinking they are some weird theoretical construct.
Medical imaging is a place where positrons are used in everyday life. Specifically, PET imaging or positron emission tomography in which a tracer dye is injected into the body. The tracer is usually biologically active, so that it is taken up in different amounts by different tissues. The tracer emits positrons which annihilate when they meet an electron and produce gamma rays which are then used to image tissue.
