network will behave. It's hard as hell, we're just not very good at that; electronic computers can do it much better.<br><br>As for pattern recognition we still have an edge over the machines, but I doubt our superiority will last another decade. <br>

Similarly when computers emulate the pattern recognition tasks that we are good at, they are thousands of times slower than us... <br>
<br>The difference of course is that computers keep getting faster, and we stay the same (so far). Therefore, even if computers are thousands of times slower at pattern recognition, someday computers will be thousands of times faster than they are today, and then eventually a trillion times faster.<br>
