Back when I worked at Lucent Tech, before the Dot Com crash, I invested a lot of money in a company that installed a fiber optic underwater cable around North and South America. I was like a ring of fiber. The company went belly up. The reason was because one strand of fiber optic cable can be split indefinitely. Siemens made a switch that could do the job. Very soon after the crash, my job became one of the many casualties . To make things worse, I was heavily investing in all Tech stocks in 2001.
