In summary, the conversation discusses the possibility of using antimatter as a fuel for rockets. While it is theoretically possible, there are several challenges such as the lack of available antimatter, difficulty in storing it, and its high cost. Some suggest using positrons as a more viable option due to their lower production of gamma rays, but the cost of producing and storing them is still a major obstacle. The conversation also briefly touches on the idea of using black hole power as a potential alternative. However, the current technology and understanding of antimatter make it a challenging and unrealistic option for spacecraft propulsion.

It is just a slight step from "impossible"... and I really hate the word impossible.

Roughly the same factor of a billion or more is what you need to get to the moon by flapping your arms. Sometimes the word "impossible" is the right one.
