[@Willy Vereb] They are not a list of energy sources, but rather technology bases/achievements/whatever you want to call it. Think of the whole bundle, form construction through power generation to weaponry.

Antimatter reactors are damn simple though due to containment issues they might be more difficult than fission power. Granted, realizing chain-reaction was downright brilliant, without it fission would be around the same difficulty as fusion. Discovering some molecule whose electric fields can safely store antimatter without containment devices might also happen the same way.
Otherwise antimatter has just two concerns:
- building a heat powerplant to handle its energy
- radiation protection
Neither are that difficult compared to fission reactor concerns.
Antimatter can easily be described as "nuclear energy for dummies".
I don't bore you to death with other examples but I think I demonstrated my point.
