Chen Xu had learned about communication technology from a learning machine in his last dream. Originally, he intended to start in this direction.
However, the professional nature of this industry was too strong, the barriers to entry were high, and the required investment was substantial. Moreover, although he had learned maintenance and principles and knew how to repair, how to actually manufacture them was something he could only fumble through by himself.
Similarly, since he wasn't from the industry, all his knowledge came from the learning machine. Perhaps his insights were advanced, but his foundation was weak, and whenever he talked with professionals from the industry, he would expose the fact that he was somewhat of a novice.
Even if he managed to produce an outstanding product, breaking into the market would likely be very difficult.
He had thought of these unfavorable factors and was sufficiently psychologically prepared.
