Is Anti-Matter a Good Thing?

It's incredible to me that almost 100 years after we've discovered anti-matter we still don't really know the answer to that. experimentally it turns out to be surprisingly tricky to do experiments with anti-matter right and specifically you're talking about measuring i guess the gravity of a particle. It's hard to kind of talk about the gravity of tiny little particles because they feel very little gravity sogravity is super hard to measure for small things as it's swamped by everything else.
