Reply to comment by minormajorseventh in Physicists nail down the most precise value yet of the electron magnetic moment. A newly measured value of an electron’s magnetic moment — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. by MistWeaver80

Some quick research shows that there are people that have been trying to develop electron spin-based transistors for about 30 years now. The name of the transistor is spin transistor and the field of engineering based around developing stuff using electron’s spin property is called spintronics.

It doesn’t seem like they’ve had much success, but handling things with single electrons is extremely challenging since they’re quantum systems. Everything is probabilistic in nature and challenging to manipulate. Current transistors are having physical limitations due to being so small that electrons can tunnel to where they shouldn’t be (or so I’ve been told. I haven’t fact checked this. I’m not a hardware guy)

I’m pretty cynical towards particle physics, but I’m all for attempting challenging engineering
