Who’s smarter — you, or the computer or mobile device on which you’re reading this article? The answer is increasingly complex, and depends on definitions in flux. Computers are certainly more adept at solving quandaries that benefit from their unique skillset, but humans hold the edge on tasks that machines simply can’t perform. Not yet, anyway.
Computers can take in and process certain kinds of information much faster than we can. They can swirl that data around in their “brains,” made of processors, and perform calculations to conjure multiple scenarios at superhuman speeds. For example, the best chess-trained computers can at this point strategize many moves ahead, problem-solving far more deftly than can the best chess-playing humans. Computers learn much more quickly, too, narrowing complex choices to the most optimal ones. Yes, humans also learn from mistakes, but when it comes to tackling the kinds of puzzles computers excel at, we’re far more fallible.
Computers enjoy other advantages over people. They have better memories, so they can be fed a large amount of information, and can tap into all of it almost instantaneously. Computers don’t require sleep the way humans do, so they can calculate, analyze and perform tasks tirelessly and round the clock. Notwithstanding bugs or susceptibility to power blackouts, computers are simply more accurate at pulling off a broadening range of high-value functions than we are. They’re not affected or influenced by emotions, feelings, wants, needs and other factors that often cloud the judgement and intelligence of us mere mortals.
On the other hand, humans are still superior to computers in many ways. We perform tasks, make decisions, and solve problems based not just on our intelligence but on our massively parallel processing wetware — in abstract, what we like to call our instincts, our common sense, and perhaps most importantly, our life experiences. Computers can be programmed with vast libraries of information, but they can’t experience life the way we do. Humans possess traits we sometimes refer to (again, in the abstract) as creativity, imagination and inspiration. A person can write a poem, compose and play music, sing a song, create a painting or dream up a new invention. Computers can be programmed to replicate some of those tasks, but they don’t possess the innate ability to create the way humans do.
What do experts in artificial intelligence make of all this? Let’s start by defining what we mean by “smarter” or “more intelligent.” Intelligence has two components, says
Professor Shlomo Maital, Senior Research Fellow for the S. Neaman Institute at Technion – Israel Institute of Technology. One is the ability to learn, the other is the ability to solve problems. And in those areas, computers can be smarter than humans.
“Today, computers can learn faster than humans, e.g.,
(IBM’s) Watson can read and remember all the research on cancer, no human could,” says Maital. “With deep learning, Watson can also solve a problem, for example, how to treat a rare form of cancer — and it has done so. So in that sense, computers can be smarter than humans.”
Some of that’s rethinking how we approach these questions. Rather than obsessing over who’s smarter or irrationally fearing the technology, we need to remember that computers and machines are designed to improve our lives, just as
IBM’s Watson computer is helping us in the fight against deadly diseases. The trick, as computers become better and better at these and any number of other tasks, is ensuring that “helping us” remains their prime directive.
“The important thing to keep in mind is that it is not man versus machine,” says Mallick. “It is not a competition. It is a collaboration.”
