The first two statements are false:
1. Chinese monks discovered gunpowder in the 9th century CE, during their quest for a life-extending elixir. The key ingredient, saltpeter, had been in use by this same culture since the late centuries BCE for medicinal purposes. It was found to be incendiary and immediately applied to warfare. (source:

2. Drones, or unmanned aerial vehicles (UAVs), were formally invented during World War I. Their very first use was as aerial targets for military anti-aircraft training and as early aerial torpedoes (such as the 1917 Kettering Bug). (source:

The third statement is correct in that the initial AI programs were applied to logic games like checkers and chess.
If you think man will ever use any new technology for anything other than warfare I have a bridge for sale.
