Yeah, and antimatter converts to pure energy with e=mc^2 what means that 60 grams contains like Hiroshima worth of energy

In theory yes, in practice we have absolutely no idea how to actually do that and use the energy in an efficient or practical way. Even just on paper without limitations of technology or costs, we have no idea. Physics simply isn’t as clean or neat like that in real life.

adding to this comment, the best way that we currently know how to extract this energy is using spinning black holes, with theoretical efficiency of ~42% (answer to the universe)(src: a minute physics video precisely on this). the naive solution to just touch them gets like 0.01-0.1% of total energy, so in bad case, we need trillion years.
