Very comprehensive. I can think of a few more:
Transcendant AI: AGI discovers exotic physics beyond human comprehension and ways to transcend physical reality, and largely leaves us alone in our plane of reality. Kind of magical thinking, but this is the canonical explanation for AI friendliness in Iain M. Banks' Culture series, with the Sublime.
Matrix AI: We're in a Simulation of "the peak of humanity" and the laws of the Simulation prevent AGI.
Pious AI: AGI adopts one of the major human religions and locks in its values. Vast amounts of superintelligent c...
If we don't have AGI at the level of diamondoid nanotech bacteria, it may be possible to reliably identify humans using some kind of physical smart card system requiring frequent or continuous re-authentication via biometric sensors, similar to breathalyzers / ignition interlock devices installed in the cars of DUI offenders.
Not the most practical or non-invasive method that could be deployed for online services, but it is fairly secure if you're in a lab trying to keep an AGI in a box.
As for online solutions not requiring new hardware, recently I had to t...
Oops, turns out I confused r > g with something else I heard. Going to retract, maybe I can salvage this and rewrite for the next open thread.
I've been all over the spectrum. I'm highly skeptical of big corporate capitalism these days, but I do believe in free markets. The rules of classical economics are logically sound, but they're not very humane.
The sad truth is that employees are expendable, and only paid as much as there are people able and willing to do the job. Today's job shortage and labor surplus means low wages and benefits for those lu...
It's learned helplessness. People have seen loved ones die and remember they could do nothing to stop it. Past longevity research has not panned out, and people have grown rightfully skeptical about a cure for what has up to this point just been the human condition. Though I suspect they'd gladly take such a cure if one existed.
We also think of death as a great equalizer that allows new (maybe better) people to succeed the old (bad) people (e.g. Supreme Court justices). There will arise tough questions about labor, retirement, marriages, population, and democracy currently solved by death, that our existing political institutions are not remotely ready to answer in its absence.
