Awesome and thanks. FYI. This Japanese magician was on Penn & Teller: Fool Us S5E7 on Monday night: http://www.cwtv.com/shows/penn-teller-fool-us/imagine-magic-dragons/?play=0da874b1-35ad-422b-8497-a07c136013a5 ...

Was hoping for an actual experiment.

You cannot both "detect" a photon/electron before it "enters a slit" and have it go through and "detect" it again at the back. That part is (probably) hogwash.

Detection at this scale really means fatal crash or at least deflection.

From what has been observed it would appear that in such an experiment an individual electron takes all the possible paths through both slits and the "waves" that "interfere" are waves of probability of the particle passing through detection points.

While it might as well be magic, really, QED does have observable rules, and this video might make it appear as though one could change the outcome by blinking an eye, which is not the case.

To make any headway stop thinking about tiny marbles. Think about tiny cartoon characters moving so fast they are smudged to invisibility whirring their tiny appendages around - you can only tell which particle and where it is if you swat it or it hits a wall and stops moving. There is no "detect but keep going as if nothing happened".

Maybe it's just me. but camera tricks and GC are not magic.

There is a generally held belief that consciousness is a mystery of science or a miracle of faith; that consciousness was attained instantly (or granted by god), and that one has either attained self awareness or has not.

I don't believe any of that. I believe like all things in biology, consciousness evolved to maximise a benefit, and occurred gradually, without any magic or mystery. The closest exurb1a gets to that is when he says at 6:28:

"Maybe evolution accidentally made some higher mammals on Earth self-aware because it's better for problem solving or something"

We need to know what other people are thinking and this is the problem that consciousness solves. If a neighbouring tribe enters your territory then predicting whether they come to trade, mate, steal or attack is beneficial to survival.

Initially this may be done through simulation - imagining the future based on past experience. A flood approaching your cave is bad news. Being surrounded by lions is not good. Surrounding a lone bison is dinner. Being charged by a screaming tribe is an upcoming fight.

We could only simulate another person's actions, but we had no experience that allows us to simulate another person's thoughts. You may predict that giving your hungry neighbour a meal may suppress their urge to raid your supplies but you still can't simply open their head and see what they are thinking.

Then for the benefit of cooperation and coordination, we started to talk, and everything changed.

Communication not only allows us to speak our mind, but allows us to model the minds of others. We can gain an understanding of another person's motivations long before they act upon them. The need to simulate another person's thoughts becomes more nuanced and complex. Do they want to trade, or do they want to cheat?

Yet still we cannot look into the minds of others and verify our models of them. If we had access to an actual working brain we could gradually strengthen that model with reference to how an actual brain works, and we happen to have access to such a brain, our own!

If we monitored ourselves then we could validate a general model of thought against real urges, real experiences, real problem solving and real motivations. Once we apply our own selves to a model of thought we become much better at modelling the thoughts of others.

And what better way to render that model than with speech itself? To use all of our existing cognitive skills and simply simulate others sharing their thoughts with us.

At 3:15 exurb1a referenced a famous experiment that showed that we make decisions before we become aware of them. This lends evidence to suppose that our consciousness is not the driver of our thoughts, but a monitor - an interpretation of our subconscious that feeds our model of how people think.

Not everybody is the same. We all have different temperaments. Some of us are less predictable than others, and we tend to avoid such people. Some are more amenable to co-operation, others are stubborn. To understand the temperament of one we must compare them to another. If we are to compare the model of another's mind to our own, and we simulate their mind as speech, then we must also simulate our own mind as speech. Then not only are we conscious, we are self-aware.

Add in a feedback loop of social norms, etiquette, acceptable behaviour, expected behaviour, cooperation and co-dependence, game theory and sustainable societies and this conscious model eventually becomes a lot more nuanced than it first started - allowing for abstract concepts such as empathy, shame, guilt, remorse, resentment, contempt, kinship, friendship, nurture, pride, and love.

Consciousness is magical, but not magic.

Appearance wise, I'd say he spent most of his life sitting in front of the magic mirror. (not to be confused with the black mirror)

So the privately run "family detention centers" like the one set up in Dilley, Texas, by the Obama administration were acceptable, but this is a step too far?

This shit didn't magically appear out of thin air. You can trace it throughout the entire history of the US: the separation of children from their parents during slavery, the forceful removal of children from reservations and their placement into "Indian schools", the mass incarceration of primarily minority youths for the crime of being poor, and physical removal of parents in foreign nations by incinerating them in drone strikes, etc.

This shit is despicable, but it's not a deviation from previous actions -- it's just the next step. And for Maddow to "break down" over this... There are Syrian refugees living in the apartment building across the street from me. How many Syrian, Libyan, Somali, Pakistani, Afghani and Yemeni children have been separated from their parents by US bombs and missiles? Never stopped Maddow from warmongering.
