Future Computers (HW #3)

Of course, computers will be flourished in our life more than before. Not only me but also everybody will want useful tools based on computer technology. One possibility I imagine is that a house will be managed by a computer so that people in the house can know the condition: solar power, temperature, humidity, health( see “Computer Gift 2”), and so on. The people will also be able to check them by a cell phone or a PC at their office. It will be very convenient to care a house and his or her family, but the big problem is that it is easy to be peeked by a third party. Then, security system will be reinforced by a new security program. The anxiety is what I cannot imagine how it costs...
By the way, I have another fancy in the future computers. It is definitely impossible right now, but, to my interests in science fiction, I expect computers to have performance for translation of our brain signals.
