In which sense are brains similar to the devices we currently call computers, and in which sense not? What’s the difference between what they can do? What’s the status of current technology. And is Roger Penrose right in saying that Gödel’s theorem tells us human thought can’t just be computation? At the end of this video you will know the answers.

Love the Dr. Who dress! 🙂
I love your sense of humor… it's so…. German. 🙂 I loved Germany when I was there for a few years in the late 80's.
"It'd take an infinite amount of time, like me trying to properly speak English."
Trust me, everybody has issues with speaking English, even native speakers.
I don't understand the counterfeit computation?? Please make a detail video on this topic in more detail than previous video
if so, I guess I'm due for a driver update amirite
Your English is pretty good. At first I thought you were English with a speech impediment, then I realized you just German and became impressed.
"and maybe you'd have 90 million if…" she says as he smokes some weed. I love this channel.
http://youtu.be/hDpEg881BnI this is a video on this channel about Gödel’s theorem
Who said neurons are not binary? They are. Basically 2 states: exited (generating spikes) and passive (no spikes). Yes, neurotransmitters and synapses are non-binary but we can describe them with mathematical models pretty well.
So one can say that human brain is a computer made of neurons connected in neural nets with complex topologies.
Please don't bring quantum physics to the brain operation, otherwise I'd question that you are really familiar with the subject.
The first Turing complete computer, the Z3 was electromechanical, rather than electronic.
Roger Penrose is absolutely right.
I’m probably thinking about this too simplistically, but if we turn the question around, is the answer to the question any clearer? Are computers brains?
First of all, this makes more sense temporally, since brains came first. Second, it seems to belie the reason why we usually ask the question the other way around: because computers are something we made, it’s much easier to describe them, and thus ask if a piece of biology meets that description. On the other hand, if we’re asked to describe a brain outside the frame of a definition of “computer,” it becomes much more difficult to say that a computer is a brain than it is to say a brain is a computer. On some level, there’s surely some non-transitive equivalence, but that probably doesn’t make sci-fi writers very happy.
For ppl who don't know what a gallon of water is… It's alot of water! 🤣
Ever consider that society is a network of incomplete and inaccurate databases?
No! No.pie. Pie triggers my gout.
Unwise 🙅♀
Wisen't 👈
What a coincidence, We are discussing this very topic in my Cognitive Psychology class exciting info
If I could implant a floating point processor in my brain to handle all the math I struggle with, I would almost be as smart as my phone.
In all fairness your english is good. There would be no point in training out your accent as it doesn't make comprehension a problem and at this point your accent does more to show where you're from and who you are
A gallon is four liters. No it isn't but it's close enough you wouldn't be able to tell with your eye
"…But in case you are good at multiplying 20 digit numbers, you should totally bring that up at dinner parties. That way, you'd finally have something to talk about…" – BRILLIANT!
