Indeed Majorana fermions are completely unseen/unconsidered outside of Neutrinos. In fact all Standard Model fermions except Neutrinos are proven to be Dirac fermions
The Majorana particles in Microsoft's set-up are "quasi-particles". They aren't really fundamental particles, but excitations in the system which behave (roughly, in some appropriate sense) like particles. They aren't neutrinos.
You are confusing quasiparticles with fundamental particles. If we were to observe a Majorana topological state, this would have no bearing on the properties of the neutrino.
Also to say Majorana fermions are not considered outside of neutrinos is a patently ridiculous and ignorant statement. There is absolutely nothing in physics to say the only particle that can possibly be Majorana is a neutrino. For example, there have been theories of Majorana dark matter which are a consideration of fundamental Majorana particles outside of neutrinos.
Huh? This has nothing to do with neutrinos.
The chip is literally called Microsoft Majorana 1
