Why Brains Are Different From Computers

[Vladimir]

Nope - iirc, the Earth itself has been around for 4 billion years, cellular life only appeared approximately 2 billion years ago.

Earth is around 5 and there is evidence to suggest life began between three and four billion. Almost as soon as it could, it did. You're thinking cellular; is that eukaryotic or prokaryotic? Point is the date keeps being pushed back and is far different from computing.

Touche - upon further reading, there are prokaryote fossils dating from approximately 3.5 billion years ago (give or take a couple hundred million years).

But ultimately i should be more coherent and specific in my point, in that i'm referring to multi-cellular life with the basis for a brain, no matter how primitive. Thus, the human brain hasn't been in development for however many years it can finally be agreed on that life has been around for - the human brain has been in development since whenever the first multi-cellular life developed a nervous system.

But that still doesn't answer my question - where did Reise's comment on 7 billion years come from?

Yea, I watch way too much science channel. There have been successful experiments where rat brain cells were used to control computer chips. The computer isn't a brain, but a product of and tool for the brain. He also said "several" not seven.

He also said "several" not seven.

Thank you.
sev·er·al /ˈsɛvərəl, ˈsɛvrəl/ –adjective
1. being more than two but fewer than many in number or kind:

Maybe I stretched the definition of the word and 'few' would have been more appropriate, but I meant between 2-4. I didn't know the exact number and didn't feel like looking it up. 2 billion or 5 billion, it it doesn't matter compared to 60 years or whatever, 10^1 vs 10^9 = damn, who cares what the multiplier is.

And now from a debate on how long life has been about, i swiftly bring it to the English language - since when does 'several' mean 2-4? TO my knowledge, several has always meant seven of something i.e i have several buns

Several means two or more and generally used for an approximation.

The brain is a set of specialised cells. There development (RNA/DNA) can be linked back to the first set of cells not just neural pathways. One evolved from the other, it doesn't stop the process starting at inception of cells.

Never heard of that. Several has always just meant a "couple" to me.

You must be a Mormon then. A couple is two. Like a married couple.
