No mention of the truly magical rocks that have a measurable aura and mostly won't try to kill you, magnets?
HOW DO THEY WORK???
11 years ago... I wonder if he'll revisit the topic with his current deep dives into relatively...
what current deep dives into relativity are you talking about? WHAT AM I MISSING, PLEASE RESPOND, I NEED TO KNOW ππππ’
Veritasium's latest videos. Like the last 4 or 5.
Some rocks are so magical that they can think and show us cat pictures
well they can do the sums, but that may be a far cry from thinknig
by that logic our brain is just passing neurotransmitters along.
No, a computer is just boolean logic. I'm not being reductive, that's literally all you need.
When people say that thinking is just complicated enough computation, that's an assumption. A particularly convenient assumption, given all the computers we have lying about.
if we ever emulated the complex interplay of chemicals and electricity in our brains using a computer's boolean logic, wouldn't that be thinking?
A brain is several billion living nerve cells all doing their thing, acting and reacting to one another, concurrently. A computer is only ever doing one task at a time, but at a fast enough pace as to give the illusion of multi-tasking.
Emulating a whole brain (everything, not just simplified neural networks, but the actual nerve cells themselves) is currently far beyond what computers are capable of. More then that, not every natural phenomenon can be described algorithmically! It's entirely possible that consciousness is non-computable.
i know we don't have that technology right now. i see it as very plausible in the future.
Itβs entirely possible that consciousness is non-computable.
thats a hell of an assumption, is thinking the same as consciousness? how would consciousness be non-computable, if our brains are composed of discrete computation units (the neurons)? granted they are very different from computers, but i can see it being emulatable with enough processing power to account for all the variables.
we don't know for a fact only fleshy brains composed of neurons are somehow capable of experiencing it. do we know what consciousness even is?
is that even how we define "thinking" too? why would a theoretical future ai that could theoretically have a logic process like ours not be considered "thinking"?
Yes, it's an assumption to say consciousness is non-computable. But it's also an assumption to say it is computable. Not really a phenomenon we understand.
I agree that fleshy brains are probably not the only things capable of producing consciousness. I think it's actually fairly likely that a machine could be made that reproduces it, I'm just... really skeptical that it's gonna look anything like a Turing machine. It would certainly be convenient if it did.
As to brains being made of discrete units... there's some evidence to suggest it might not be. When you put a person (or any living thing) under general anesthetics, the thing the anesthetics target is microtubules within cells. And microtubules themselves have quantum mechanical properties. They've been shown to er, "do", super-luminescence in lab experiments (I don't understand quantum).
Admittedly, that's a lot of correlation and almost no direct example of causation. But it does suggest there's... something... there that needs more examination and research.
yeah you are right. but "we don't actually know" doesnt make for a fun thought experiment.
i think if we ever figure out a way to emulate a brain, theres no reason it shouldnt look like a turing machine, if thats even possible at all.
id love to see that evidence if you have it. its a subject im interested in.
Some, like sulfur, have an aura of stink.
This is false most common form of rock magic is transistors
Halite aura provides tastiness, although it's technically a mineral not a rock.
Dammit Marie!
Reminds me of an old RPG parody that had a spell like this:
Gas Cloud: To prepare, the caster must eat two loaves of bread and as many plates of pea soup as they can...
Rocks produce strong fire auras in water. Congrats on the nuclear reactor. You're quite the "alchemist"
Ok. This actually made me laugh. Thanks.
I thought it was a good fit for this community. Good to know my repost wasn't just spammy.
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
