Physics of the Future Chapter 2 : Future of AI

Okay so today I am reviewing chapter two of Michio Kaku's Physics of the Future(ISBN 978-0-385-53080-4)), and the topic is Future of AI. In this chapter he talks about robots and their developments.
Robots are said only to follow programming, and can't recognize patterns yet. It will take many years before they are smarter than a mouse. However since a robot can follow commands in its programming it can appear realistic enough as a human. For example Honda's ASIMO (Advanced Step in Innovative Mobility) is a robot that resembles a boy wearing a helmet and a backpack. Its about 4 feet tall, can walk like  a human and do many other things. It can run, climb stairs, and even can talk. The only thing that makes you realize its all programming is it takes a long time to recognize objects, and needs constant new programs to run on. Even walking for ASIMO has to be programmed before, so that it won't trip over any objects.
Another obstacle is common sense. Robots can tell what words mean, in definition. But when it comes to a phrase like "Rewards are better than Punishments", a robot can't understand the deeper meaning, or message behind it. Normal robots look at an object and divide it up into simple shapes. If a robot wouldn't do that but rather recognized the whole object as one item it will be even more intelligent than we are.Other robots can be programmed to excel at one task but at others will fail, like chess playing robots. Chess playing robots can beat even the best players, but in subjects like English, or Science will fail. Robots only have 2 obstacles preventing them from being even more intelligent than we are. The first, as you already know is recognizing what objects in the room are instantly. For a robot it will take more than an hour before an a object, like a sofa is no longer just a jumble of circles and squares.
ASIMO weighs 119 Lbs

In the future he says, robots will be hidden out of our view, and will appear like small animals and insects. They will perform the uneasy tasks, or tasks that we find unpleasant. Other robots will be life like and be able to do a job without any script, but will be limited to only a certain number of tasks. This category will include: robot surgeons and robot cooks.
