Since we have no idea how the brain works...</i>"<br /><br />Just to be clear, while we have no idea how the WHOLE brain works, how parts of it work is well known. For example, the pre-processing done by the visual cortex. The way Moravec got those numbers is to consider the grams of brain material required by the human and mammalian brains to do that processing and compare it to the computer power required to do that same processing in real-time. Then, he assumes that the rest of the brain is more or less comparable, leaving a straightforward calculation to translate between a brain (cortex) of a certain weight and processing power.<br /><br />Even if he's off by a couple orders of magnitude, unless the exponential trends stall out soon, we'll still see $1,000 worth of computing power have the same processing power as a human brain within a few decades.<br /><br />Unless, of course, the brain does quantum computing.Brethttps://www.blogger.com/profile/15063508651955739056noreply@blogger.comtag:blogger.com,1999:blog-5806884.post-8361212226480361602015-09-19T12:32:08.798-07:002015-09-19T12:32:08.798-07:00... that may be true using today's technology,...... that may be true using today's technology, but we don't know what's around the corner. <br /><br />A good friend who's also a very good orthopedic surgeon advised me to live with my problematic hands because he doesn't know anybody whom he would recommend who could make things better and many who could make things much worse.<br /><br />However, other than pain if I try to do something intricate or pick up something heavy, it hasn't changed my life, but in the bad old days, I wouldn't be able to live without assistance because doing routine domestic chores like making butter, kneading bread, milking cows, etc. would have been out of the question. <br /><br />Luckily back when, few people lived to tell the tale of their woes with their 80+ year old brains and bodies.erphttps://www.blogger.com/profile/09826044412670324694noreply@blogger.comtag:blogger.com,1999:blog-5806884.post-79350705527119413332015-09-19T12:09:04.369-07:002015-09-19T12:09:04.369-07:00I think that in a world where 96% of men are crazy...<br />I think that in a world where 96% of men are crazy about football but only about 0.00001% play handball, you are swimming upstream.<br /><br />Time is also not your friend. The genes that code for forelimbs with several (most often 5) digits are over 400 million years old. If you think of evolution as a kind of haphazard R&D program, it's reeaaal slow. <br /><br />Some years ago, I interviewed an orthopedic surgeon, who told me she didn't do hands and considered very few surgeons capable of doing it: the intricacy and compactness make it difficult.<br /><br />A robotic hand may be quite a bit bigger than ours.<br /><br />Harry Eagarhttps://www.blogger.com/profile/04196202758858876402noreply@blogger.comtag:blogger.com,1999:blog-5806884.post-64712397658815998692015-09-19T06:51:35.238-07:002015-09-19T06:51:35.238-07:00Bret, I hadn't ever really thought about how d...Bret, I hadn't ever really thought about how difficult hands are to mechanize, and they probably aren't a patch on perhaps the most versatile end effector out there: an elephant trunk.<br /><br />BTW, I think your chart is a bit brave in 10^9 MIPS as "Brain Equivalent". Since we have no idea how the brain works, not only do we not know how many MIPS brains execute, we don't even know if how it does what it does relies at all on anything like discreet instructions (never mind being a binary state machine).<br /><br /><i>[Harry:] You know what else cheap computing might do?

Prior to the late 60's early 70's (yesterday in my world) people needed to carry cash or travelers' checks and freguently had to find a bank to cash them because local merchants didn't want to be bothered ... <br /><br />When traveling abroad, it often meant a trip to the American Express office, not a problem in Paris, but a big one in Moose Jaw (yep, Peter, we were there and had a wonderful meal prepared by a master French chef). Who'da thunk it. The owners of the small hotel and restaurant where we stayed took our personal check on a New York City bank no less and when we got back home, I wrote a nice thank you note for the lovely visit and they wrote back and we exchanged notes for many years until ...<br /><br />I was telling a young friend (30ish) about the trip we took to the Canadian Rockies and how fabulous it was except for the trouble we had getting money. She was stunned and thought I was kidding around with her.<br /><br />Even forgetting traveler's checks, imagine the trauma it would cause if one had leave one's car and open the garage door manually? I'd need strong psychotropic medication to even contemplate the horror and living without a nuke-atorium -- unthinkable.erphttps://www.blogger.com/profile/09826044412670324694noreply@blogger.comtag:blogger.com,1999:blog-5806884.post-76401158299757465402015-09-17T12:13:04.868-07:002015-09-17T12:13:04.868-07:00Howard,

I tried a number of voice recognition programs, but they didn't suit me. <br /><br />This morning, one of my most tech savvy friends posted a FB joke about Windows 8. Y'know, as long as a company with the resources of Microsoft can be stupid enough to develop and emit W8, I think claims about the potential of computers to change things for the better are overblown.Harry Eagarhttps://www.blogger.com/profile/04196202758858876402noreply@blogger.comtag:blogger.com,1999:blog-5806884.post-41203240431398433562015-09-11T13:57:48.519-07:002015-09-11T13:57:48.519-07:00... interesting Bret.
