Unlike conventional micro-transistors, magnetic tunnel junctions don't use the electrical charge of electrons to store information, but take advantage of a quantum-mechanical property that electrons have, which is referred to as "spin." Known as spintronics, computing technology based on magnetic tunnel junctions is still very much in the experimental phase, and applications are extremely limited. For example, the technology is used in aircraft and slot machines to protect stored data from sudden power outages. This is possible because magnetic tunnel junctions process and store information by switching the orientation of nano-scale magnets instead of moving electrons around as regular transistors do.

"For a close reader of Moyn's work on human rights the differences between his two works are head-spinning.  Where Last Utopia attacked the very idea of historic continuity in explaining the human rights movement that emerged in the 1970s, Not Enough builds an entire narrative on continuities. The result is an aspirational history for a reformed human rights movement, a history of roads not taken - with respect to equality, in particular, which Moyn elevates to the 'original' position - that can still be reclaimed.  Not Enough lacks the skepticism that Moyn employed so effectively in The Last Utopia to explain how disconnected contemporary human rights was from its claimed antecedents and undermines arguments in both books. In addition, by not heeding his own lessons from Last Utopia, Moyn understates the emergent human rights movement's inability to contest what became neoliberalism. As someone who confronted those issues at the time, it is harder to dismiss the claims of complicity."
