We can calculate the path of a particle detected by our instruments by adding together the infinite number of paths it could have taken, Feynman found how to do this.

>can easily explain the phenomenon of the interference pattern

I think even Feynman would say that "explain" is too strong a word, it works but it's very hard to form an intuitive mental picture from it. He once said "I think it's safe to say that nobody understands quantum mechanics", and "It's pointless to keep asking yourself how things could possibly be so crazy, they just are". Feynman was not big on philosophical interpretations but he did like Many Worlds the best, or at least disliked it the least.

>our history would constantly be changing around us by large magnitudes.

Some physicists such as Murray Gel-Mann like everything about the many Word's Interpretation except the name, he calls it the Many histories interpretation.
