# game: inject irrationality into a game scenario; when a player will be their own worst enemy
<< in game theory, a game is defined as any type of scenario where there's an interaction between different decision-makers, or players, each of whom has well-defined preferences. >>
<< previous analyses assume the decision-makers always do what is best for them-they are fully rational-which is not always realistic. >>
<< So SFI Professor David Wolpert and economist Justin Grana, a former SFI postdoctoral scholar, wanted to inject some humanity into the players. They analyzed games with players who were subject to error, or "boundedly rational." >>
<< Our analysis shows that in many of these situations, a player will be their own worst enemy; >> David Wolpert.

# acad: Prometheus vs Pandora interplay
<< Some of the most important rules we need to discover are about how to use technology and, just as importantly, how not to use it. >>
<< The great institutional economist Clarence Ayres wrote about how technology becomes incorporated into our lives in a way that is roughly equivalent to the way tribal societies use totems to interact with each other. >>
<< Every inventor is both a Prometheus stealing fire from the gods, and a Pandora unwittingly releasing a swarm of potential evils on the world. The competition of ideas between hype and doomsaying allows us to discover helpful rules which deal with both. >>
<< Technology doesn't come with a ready-made rulebook for how to use it. We have to discover this in a process of trial, error and argument. And for this the doomsayer is just as vital as the visionary. >>

AA << introduce the flip-flop qubit, a combination of the electron-nuclear spin states of a phosphorus donor that can be controlled by microwave electric fields >>
<< to encode quantum information in the electron-nuclear spin states of 31P [phosphorus] donors in silicon, and to realize fast, high-fidelity, electrically driven universal quantum gates >>
<< a credible pathway to the construction of a large-scale quantum processor, where atomic-size spin qubits are integrated with silicon nanoelectronic devices, in a platform that does not require atomic-scale precision in the qubit placement [..] and, with realistic assumptions on noise and imperfections, are predicted to achieve error rates compatible with fault-tolerant quantum error correction >>
