First, you seem to think that humans are somehow special and above other species at who's expense "we became the masters". Would truly superior being not care about less superior ones, at the very least (not to mention intentionally killing them, often for fun).
Second, fighting these tendencies will make everyone's lives better. These are basic things: less wars, crimes, better air quality, increase in happiness. I believe greed and corruption and related qualities are what prevents that from happening now.
I guess what I'm saying is that we got caught up with technology so much that we put all out hopes and dreams into it. But it cannot (in any near future) make us morally and spiritually superior. And why even bother? There are other ways to go about doing that. Education. It's a much longer and harder route, but it seems to be the proper one. Otherwise we are just waiting for a tech product what would fix all our problems at the push of a button - ridiculous.
