Came here to say something like this. One big problem in the field is detection. They are detected only indirectly using current methods. And there are other particles that could trigger a detection. Majorana particles have interesting properties in theory, but these properties have yet to be validated. The most interesting, and useful for quantum computing, is the ability for a pair of Majorana Fermions to "record", in the form of a qubit, how many times they have been wrapped around each other. But this requires having two, and being able to move them at will. Every new material we find them in is a chance for success.
