I was born in New York City and grew up in its suburbs. I have been a fan of science fiction for over 50 years. I worked as a technical writer in California in the early 1980s, then crossed the great water to Japan. After a few years, I migrated south to Thailand and then Indonesia. I have been living in the hometown of my wife in Central Java since before we married in 1997.
Suppose humanoids from another star system came to earth not as mentors or monsters but as trading partners. Earth could not compete with the economy of scale of their production and distribution network. A multicultural team of earthlings develops time travel that is based more on spirituality than science. They summon a man from the 20th century to help Earth emerge from its planetary doldrums.
