There were two types of brain chip pico surgery performed by humans in the year 200,000. The first was a small processing chip implanted at the base of the skull which cost one hundred credits at Satellite Five.
The other was a receptor chip implanted in the forehead. This surgery cost ten thousand credits. When activated, the forehead opened up, exposing both the chip and the naked living brain of the implantee.
Once the receptor chip was activated, compressed news information was streamed into the person's brain. They became, in effect, part of the hardware. Their brain was the computer. However the brain only processed the information. It did not retain it after the download. In effect, the brain acted as the passive receptacle of information, without memory of the information transmitted.
