A single neuron in the brain is an incredibly complex machine that even today we don't understand. A single 'neuron' in a neural network is an incredibly simple mathematical function that captures a minuscule fraction of the complexity of a biological neuron.
Interpretation
The complexity of biological neurons far exceeds our current understanding and the simplicity of artificial neurons.
This quote compares the intricate nature of biological neurons with the simplicity of artificial neurons used in neural networks. It highlights the vast gap in complexity between human brain functions and current technologies, emphasizing that while we have made strides in AI, much remains to be understood about the brain's workings.
In practice
In a discussion about the limitations of AI technology, this quote can emphasize the need for further research in neuroscience.
AI has been making tremendous progress in machine translation, self-driving cars, etc. Basically, all the progress I see is in specialised intelligence. It might be hundreds or thousands of years or, if there is an unexpected breakthrough, decades.
It seemed really amazing that you could write a few lines of code and have it learn to do interesting things.
Most of the value of deep learning today is in narrow domains where you can get a lot of data. Here's one example of something it cannot do: have a meaningful conversation.
Imagine if we can just talk to our computers and have it understand, 'Please schedule a meeting with Bob for next week.' Or if each child could have a personalized tutor. Or if self-driving cars could save all of us hours of driving.
None of us today know how to get computers to learn with the speed and flexibility of a child.
I've been to so many manufacturing plants. I've yet to walk into one where I did not think AI solutions wouldn't help.
Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.
The work on ants has profoundly affected the way I think about humans.
We fly to 106 kilometers. We've always had as our mission that we always wanted to fly above the Karman line because we didn't want there to be any asterisks next to your name about whether you're an astronaut or not.
The conscious mind is not at the center of the action in the brain; instead, it is far out on a distant edge, hearing but whispers of the activity.
But when it has been shown by the researches of Pasteur that the septic property of the atmosphere depended not on the oxygen, or any gaseous constituent, but on minute organisms suspended in it, which owed their energy to their vitality, it occurred to me that decomposition in the injured part might be avoided without excluding the air, by applying as a dressing some material capable of destroying the life of the floating particles. Upon this principle I have based a practice.
I must confess it was very unexpected and I am very startled at my metamorphosis into a chemist.
