IBM simulates a cat’s cerebral cortex using a supercomputer. The numbers are staggering: using almost 150,000 processors and 144 terabytes of memory, the program simulated the roughly 1 billion neurons and 10 trillion synapses (connections between neurons) of a cat’s brain. Even with this massive processing power, the simulation ran a hundred times slower than a real cat’s brain. (The researchers fed the artificial brain images of corporate logos. If I were a brain in a vat, I’d want my fantasy world to be a little livelier.)
A deeper question is whether this kind of simulation is telling us anything new. It seems — and this is, of course, extremely speculative, as is everything regarding actual artificial intelligence — entirely possible that we could duplicate a human brain in silicon, yet come no closer to understanding the brain’s operation. AI might be useful, but will it ever satisfy our very human curiosity about how and why stuff, in this case, the mind, works? Who knows. When dealing with the nature of consciousness, very little is certain.
Is it insane to go through my bank statements and catalog my spending habits from the time I started living completely on my own (2006) till the present? I think it would be a good way to analyze trends in my adult life and really plan my finances and regiment my spending.
Went through some old ones this morning and remember even little purchases from 3 years ago. “Oh, I remember that 5 dollars I spent at Jamba Juice in July of 2007, that was the time Jason, Matthew and I asked that lady to take a picture of us while we crouched in a window well!” Crazy.
Not insane. I did that in September and it was hilariously awesome. I’ve actively started using my check card as often as possible so I will always have the memories.
I took this a step further and actually built an excel template where I categorized every penny spent. Groceries were broken down by “categories”, which week I bought them, & if coupons/savings were used. Eating out was broken down by types of meal, which day of the wee, & the people that I went out with
