Yes, but I want to discuss even more mundane technological
possibilities, like MagOrion.

Even plasma thrusters lack the Isp for an interstellar mission. In
order for the catalyzed fusion to be suitable for interstellar travel,
you have to count on some sort of advances in Isp.

I think the 100 year timeline is ridiculous. The first missions, which
might be possible within 100 years, would be unmanned.
