WASHINGTON — Humanity has reached a chokepoint this one C : Technical developments could cause ruinous damage to the major planet , or they could pull through humanity from its man - made quandary .
The future of civilization could be a dystopia of deflower ecosystem and malevolent automobile , or a promised land of eternal life and intergalactic civilization . At a symposium on the seniority of human civilisation here at the Library of Congress Thursday ( Sept. 12 ) , several of the Carry Amelia Moore Nation ’s lead scholarly person and futurists predicted what the coming centuries may bring .
From finding life elsewhere in the universe to developing intelligent machines, the future offers some startling possibilities.
" Everything I say today will probably be wrong , " Scientific American journalist David Biello said at the start of the outcome . [ Science Fact or Fantasy ? 20 Imaginary Worlds ]
Nonetheless , here are five of the speakers ' science - fable visions of the futurity .
1 . clime catastrophe
It ’s no surprisal that surface C dioxide levels already pose a major terror toEarth ’s climate . Unless humans figure out a way to drastically throttle their carbon footprint , the planet will continue to warm , utmost conditions will become more frequent , and many mintage and human communities will be pass over out , said Ken Caldeira , an atmospheric scientist at the Department of Global Ecology of the Carnegie Institution for Science .
Can humankind mold a respectable , stable family relationship with the biosphere ?
" The answer is no , " said Ken Caldeira , an atmospherical scientist in the department of planetary environmental science of the Carnegie Institution for Science in Stanford , Calif.
man develop as hunter - gatherers , sensitive to the indigence of themselves and their close family and friend , Caldeira said . But now , humans have created a macrocosm dominated by technology , rather than nature , where problem extend to the global shell . If drastic measures to stem global clime change are n’t taken , we do n’t know what effect it might have on human civilization , Caldeira say .
2 . Bionic world
Biology has entered a sort of renaissance , from sequencing the human genome to develop lifesaving medical treatments .
Already , the world has seen mechanical essence , prosthetic limbs and unreal organ , technologies that foretell to restore human wellness and dramatically extend liveliness duad . But as these technologies become more democratized , black hat uses will surface .
The crowing threat somebody face isbiohacking , said Seth Shostak , senior astronomer at the Search for Extraterrestrial Intelligence ( SETI ) Institute in Mountain View , Calif. Such biohacking includes everything from tinker with the genome of a computer virus to make it deadly , to inserting information flat into the brain through an implant .
Perhaps humans will even spring up an " ethics implant , " said Jacob Haqq - Misra , a planetary climatologist at the Blue Marble Space Institute of Science . Such an implant would ensure citizenry see eye - to - middle on the problem civilization faces .
3 . Artificial intelligence agency
Scientists are passionately divide on the issue of whether human race will develop information processing system that are intelligent , or " think machines . " Will HAL from " 2001 : A Space Odyssey " become a realism ?
Science - fiction authorKim Stanley Robinsondoesn’t think so . " One affair we ’ll never realize is the human brain , " said Robinson , source of the well - known " Mars " trilogy .
scientist can only learn the psyche indirectly by valuate blood menstruum and electrophysiology , which is several magnitudes broader than the point of human cerebration , Robinson say . Without understanding cognizance , how could man create a machine adequate to of it ? [ Super - levelheaded Machines : 7 Robotic Futures ]
Shostak disagrees . human race did n’t take to sympathize the details of how birds flee for arise aeroplane , he state . So why should they need to read the nous to develop intelligent computers ? And , " once you have machine that can cogitate , you may ask that to develop the next machine , " Shostak say .
get hold of to the extremum , some the great unwashed consider sound machines could conduct to"the uniqueness , " a full term popularized by discoverer and futurist Ray Kurzweil to describe the point in time at which computers surpass the abilities of the human brain .
Kurzweil predicts this will happen by 2045 , but Robinson and others are sceptical . Many people alive today will endure to find out , Shostak said .
4 . Spacefaring species
In 1969 , humans shore on the lunation . A few decades from now , mankind may be on Mars . And perhaps someday , Homo sapienswill drift the galaxy like the gang of the Starship Enterprise .
At the symposium , discussion ranged over whethercolonizing the solar systemcould pull through mankind from destruction on Earth .
" One of the destination of quad exploration should be to get some of us off the planet so we do n’t have to start from gelt if a major case go on on Earth , " sound out Steven Dick , an uranologist , author and historian of skill and the Library ’s 2014 chair in exobiology . If a large asteroid hit Earth , humanity could be wiped out tomorrow , Dick say .
Yet while the technology for postulate humans to space exists , hoi polloi still rely heavily on an Earth - like environs . Traveling to space would n’t inoculate man against catastrophe on Earth , Robinson read , and other speakers agreed . But it could dish out to give people a linear perspective on the fragility of the " pale gloomy Elvis " on which humanity lives .
5 . E.T. phones home
Few things would have as outstanding an impact on human beings as discoveringlife elsewhere in the macrocosm .
For the first time in history , mankind is poised to look for life on other planet . By necessary , man will be looking for life that resembles its own . NASA’sKepler missionsuccessfully identify hundreds of planets revolve at a habitable distance from their stars . And the SETI Institute is mind for radio signals that could stand for technical civilization are out there .
Some skeptics argue that if there were life-time , humans would have found it already . But a host of reasons could explicate its absence seizure . Maybe civilisation that have developed the technology to colonize other planets have already extinguish themselves . Or perhaps they ’re much more sound and obscure themselves from humans .
Whatever the truth , if biography does subsist alfresco of Earth , the implications for human civilisation would be enormous .
" Just roll in the hay they ’re out there would be philosophically crucial , " Shostak said .
